Authors: Vivek  , Minhas Prashant , Dikshika
Published: February 2023

Today we are heading toward materialistic progress at the cost of our health, physical as well as mental. In this blind pursuit, instead of peace we end up in stressed life. Unfortunately, neither we understand that we are under stress nor get any trainingof stress management while we study or work. In this modern world there are many diseases, disorders and complications but some complications are commonest and almost each and every human being in this modern world has it, it is stress, depression and there are many medications which claims to get relief from it but only for some duration and that too has some of its side effects but, “OM” (AUM)chanting is such a traditional practice which has beneficial effects not just in relieving stress and depressionbut can also give relief from many mental and physical complications and has of course no side effects and once if learnt properly do not need any guidance. Regularly chanting of OM) can be used in daily lifestyle can be more beneficial.Present review compiles the studies which evaluated that chanting OM mantrahas the positive effect on the human health

Authors: Yuan Luqi , Zeng Shihong
Published: February 2023

Abstract

Based on the trading data of A-share listed companies held by ETFs and the shareholding data of exchange-traded funds during 2011-2022 in China stocks markets, this paper uses the dynamic panel differential GMM model to study the shareholding ratio of exchange-traded funds and the impact of its changes on the liquidity of the underlying stocks. First, all the samples were regression and empirical results were analyzed. Then, the main board of Shanghai and Shenzhen, small and medium-sized board and growth enterprise board stocks were respectively regression to draw conclusions, and the robustness of the above research was tested. In the end, two main conclusions are drawn from the above research:
(1) There is a significant positive correlation between the shareholding ratio of ETFs and stock liquidity, that is, the higher the shareholding ratio of ETFs, the higher stock liquidity.
(2) The positive change of ETFs shareholding ratio will significantly increase the liquidity of the underlying listed companies' stocks.

Avaliação do nível de aprendizagem de manipuladores de alimentos de uma indústria de biscoitos antes e após treinamentos de BPF
Authors: Cunha Luana Maria Meireles , Lima Consuelo Lúcia Sousa de , Silva Niara Maria de Jesus
Published: February 2023

Os manipuladores de alimentos desempenham um papel fundamental na manutenção da inocuidade dos alimentos e na prevenção de Doenças Transmitidas por Alimentos (DTA). Tendo em vista a importância dos manipuladores na qualidade higiênico-sanitário dos alimentos, este estudo avaliou a percepção e o comportamento de manipuladores de uma indústria de biscoitos em Belém-PA acerca das Boas Práticas de Fabricação (BPF). Foi aplicado um questionário sobre Hábitos de BPF pessoal, foram realizados treinamentos sobre as temáticas que a Legislação vigente estabelece e também foram realizadas auditorias sobre BPF pessoal com os manipuladores da indústria. Os hábitos dos manipuladores foram comparados no período antes e após treinamentos, a fim de verificar se o número de não conformidades reduziu. Participaram dos treinamentos 96 manipuladores de alimentos, no qual foi possível identificar que os manipuladores já possuem algum conhecimento sobre BPF, no entanto, constatou-se que, mesmo sabendo quais são as práticas adequadas, nem sempre seus comportamentos são condizentes às BPF. Em relação à auditoria de BPF semanal, foi possível observar uma redução significativa do número de não conformidades, principalmente acerca de barba grande. Comprovando a necessidade de treinamentos periódicos para a capacitação dos manipuladores, com o propósito de contribuir para a melhoria da qualidade higiênico-sanitário dos alimentos oferecidos aos consumidores.

Authors: Struniawski Jarosław , Dworzecki, Jacek , Delong Marek , Fehler Włodzimierz
Published: February 2023

The analysis of the training needs for the crews of police multi-purpose Black Hawk S70i helicopters serving in Polish Police Forces has been an impulse to attempt the construction of the simulation system within the research and development project financed by the National Centre for Research and Development entitled “Helicopter Simulator for Police Aviation” consisting of three components, i.e. a training stand for a pilot (cockpit), a stand for a cargo handler, a training stand for the police officers practicing the air drop operations. The simulator is supposed to provide an opportunity to drill various emergency situations, which consequently will allow to prepare the crews and technical personnel in the full range to perform the tasks as far as theoretical knowledge and practical skills are concerned. Replacing real exercises by the training held in virtual environment will contribute to the decreased costs to be incurred by Police and increased safety for any persons participating in the actions remaining the subject matters of the said trainings. The article presents the designing assumptions resulting, among other things, from multidisciplinary research performed over the determination of the detailed training needs and equipment requirements with regards to the Full Flight Simulator. The said research was conducted in collaboration with the officers of the Police Aviation Board in the High Command of the Police Headquarters as well as the operators of the counter terrorism sub-units of Polish Police Forces.
Assessment of Financial Reporting Quality in a Developing Country Using Nice Qualitative Characteristics Measurement
Authors: Kabwe Martin
Published: February 2023

Purpose: The use of different indirect measurement methods by prior empirical studies has led to contradictory findings about financial reporting quality. Therefore, this study assessed the extent of financial reporting quality using the direct method.

Methodology: Data was collected through quantitative content analysis of annual reports and audited financial statements of 20 Zambian listed companies for the period 2012 to 2018 using a direct measurement tool developed by the Nijmegen Center for Economics (NiCE). Descriptive statistics were used to assess the extent of financial reporting quality.

Findings: The study showed that the mean and median score for financial reporting quality is 2.62(52.3%) and 2.55(51%) respectively with a minimum of 2.06(41.2%) and maximum of 3.21(64.2%). The level of financial reporting quality was moderately low. Further, relevance and comparability of financial reports were poor, and companies used only or mostly historical cost instead of fair value as basis for measurement as proposed by the IFRS for its FRQ standard. Therefore, the financial reporting quality of listed companies do not meet all the criterion set out in the IFRS conceptual framework.

Published: February 2023

The present study evaluated the effect of extracts of three spices in control of Callosobruchus subinnotatus (Bambara nut pest). The experimental design used was completely randomized design (CRD). Ginger, scent leaf and curry leaf were obtained and screened for phytochemical and proximate composition using standard laboratory techniques. The Bambara nut was subjected to four treatments (To, T1, T2 and T3) which were replicated 4 times. To was used as control while the rest were treated with the spices. Results from the study showed that mortality rate was recorded highest on 100g of ginger powder extract having percentage mortality of 93.33% (T3). It was followed by scent leaf with a mortality rate of 43.33%. The result also showed that Ginger powdered extract gave the lower mean number of holes (41) and with lower weight loss of 4.9g amongst the extracts used. Bambara nuts that were not treated with plant spice extracts gave the highest mean number of holes or punctures (211) and the highest weight loss 25.5g of nuts (To). The plant extracts were effective at controlling Callosobruchus subinnotatus, though at varying degrees and more environmentally friendly biopesticides that are biodegradable and are part of human and animal food and often used as ethno-medicines.

Published: February 2023

Entre trópicos apresenta um quadro com as distintas formas de existência das espiritualidades da Nova Era no Brasil e no México, destacando aproximações possíveis e diferenças entre elas. O conteúdo do livro está organizado em quatro grandes temáticas, que incluem etnografias situadas no México e no Brasil e reflexões teóricas sobre os estudos realizados nos dois países. As quatro grandes linhas que agrupam os trabalhos são: plantas sagradas e xamanismo; saúde e terapias alternativas; movimentos, identidades, patrimônio cultural e territórios; e ecologia e Nova Era. O livro busca, ainda, entender como a Nova Era recobre, purifica e reinterpreta diferentes aspectos das tradições e culturas vernáculas: locais, nacionais, tradicionais, ao mesmo tempo em que chama a atenção para o movimento de transnacionalização e circulação mundial da Nova Era a partir do Brasil e do México. E, nesse movimento procura apreender a semântica da Nova Era como uma mediação de processos de desterritorialização e reterritorialização de narrativas que, com seus trânsitos e intercâmbios, provocam novos híbridos e enraizamentos locais.

Hacia la puesta en marcha del registro de morosos del alquiler diez años después de la Ley 4/2013, de 4 de junio
Authors: Magro Servet Vicente
Published: February 2023

Reflexiones acerca de la necesidad de poner en marcha el registro de morosos del alquiler que se aprobó en la reforma de la LAU por Ley 4/2013, de 4 de junio, de medidas de flexibilización y fomento del mercado del alquiler de viviendas, en cuyo artículo tercero se establecía la creación de un Registro Público de Inquilinos Morosos, y, para ello, la publicación de un real decreto que regularía la organización y funcionamiento de dicho registro, destinado a que cuando un propietario de un inmueble estuviera en disposición de arrendarlo a tercero pudiera disponer de un sistema de «toma de conocimiento» acerca de la constancia de los posibles antecedentes de impago de rentas del solicitante para ocupar el inmueble. Ello evita las incomodidades posteriores acerca de la necesidad de tener que acudir a un nuevo procedimiento judicial contra el mismo arrendatario que ya fue deudor a otros arrendadores, al obligarles a acudir, también, al juzgado para recuperar la posesión. La existencia de otros registros previos con similares objetivos de control de datos permite avalar la posibilidad de la constitución de este registro.
La necesidad de regulación de las operaciones de scrip dividends como fórmula para satisfacer el derecho del socio a participar en las ganancias sociales en España
Authors: Aragón Tardón Susana
Published: February 2023

Este trabajo analiza las operaciones de scrip dividends como fórmula de retribución al accionista que permite optar entre recibir un importe en efectivo como remuneración a su participación en la sociedad o recibir gratuitamente nuevas acciones.
Estas operaciones generan ventajas, tanto para las sociedades como para los socios, ya que permiten reforzar los fondos propios sin dejar de trasmitir una imagen positiva de remuneración al accionista.
Pese a su extendida utilización, las operaciones de scrip dividends no son una figura regulada en el derecho español, sino que se han configurado ad hoc a través de la práctica societaria, mediante la coordinación de la distribución de dividendos y un aumento de capital con cargo a reservas.
Por ello, en este trabajo se identifican las características, posibles efectos adversos o deficiencias de la actual configuración jurídica de estas operaciones para realizar, con la referencia de la experiencia acumulada de los regímenes comparados (principalmente, los scrip dividends de Reino Unido y el paiement du dividende en actions de Francia), las correspondientes propuestas de mejora. La más importante de ellas, dotar a las operaciones de scrip dividends de una regulación específica en España.
Species extinction, traditional healing therapy, and religious worldview among the Tugen and Marakwet people of Kenya
Authors: Kigen Japheth , Lagat Daniel
Published: February 2023

This study sought to investigate how species extinction affected traditional herbal therapy, and how together they affected the religious attitudes of the people involved. This was an ethnographic study conducted among the Tugen and Keiyo people of Kenya in the Baringo and Elgeyo Marakwet Counties. Twenty participants were interviewed, involving 6 medicine persons, 8 people that have received traditional herbal therapy, and 6 experts on traditional medicine accessed through the snowball technique. Findings revealed that among the Tugen and Keiyo people of Kenya, traditional medicine men and women harvested roots, leaves, barks, fruits, or flowers, from indigenous trees, and made concoctions that were served to sick people to give them healing. In the Tugen and Keiyo understanding, healing from traditional medicine came as a package, involving not just the concoction, but also the rituals performed by the medicine persons. Reports have emerged that out of these practices, several ailments, common or chronic, have been successfully addressed. This study concludes traditional herbal therapy, involving the use of rituals and herbs, contributes to both physical healing of the people, spiritual healing of a community in relation to God, social healing of people in relation to their view of nature, and emotional healing of the people. This study recommends that the Christians of the Tugen and Elgeyo escarpment should campaign for the replanting and protection of indigenous trees along the escarpment.

Itinerários abortivos e Terapeutas Populares: gênero, temporalidades e saberes localizados
Authors: Porto Rozeli Maria , Galvão Fabiana Damasceno
Published: February 2023

O artigo analisa os itinerários abortivos de mulheres residentes no Rio Grande do Norte e suas relações com os sistemas de saúde local. A dinâmica etnográfica também direcionou a pesquisa às terapeutas populares, (raizeiras e benzedeiras), que fazem parte desses itinerários e são conhecidas na localidade por ‘Amiguinhas’. Diferentes interlocutores/as apresentaram relatos sobre recursos tradicionais, caseiros e alopáticos, que fazem parte dos itinerários abortivos das mulheres que buscam, junto a essas terapeutas, recursos disponíveis para (re)organizarem seus processos reprodutivos. Embora as ‘Amiguinhas’ informem que não fabricam garrafadas para abortar, se observa certa permissividade no uso de chás, ervas e garrafadas, a partir do momento em que se respeite uma determinada temporalidade no atraso da menstruação. Há maior empatia por parte das Amiguinhas em detrimento dos homens raizeiros, relativa aos dramas abortivos das mulheres. Um drama de gênero, que se estabelece nessa disputa entre saberes e poderes localizados.

Transmisi dan Transformasi Tradisi Tafsir Dari Mesir ke-Nusantara: Kajian Tafsīr Qur’ān Karīm
Authors: Anwar Rosihon , Abdul Muhyi Asep
Published: February 2023

Mahmud Yunus was the first ulama of Nusantara who expand to al-Azhar, Cairo, Egypt. He studied with several leading ulama to study knowledge of the Qur’an and tafsīr. When he returned to Indonesia, Mahmud Yunus brought with him the traditions of the Qur’anic interpretation that he had found at al-Azhar, Cairo, Egypt, then poured them into the Book of Tafsīr Qur'an Karīm. This research aims to find out the knowledge transmission that was formed between the interpreters of al-Azhar, Egypt and Mahmud Yunus, and the forms of interpretation traditions contained in Mahmud Yunus' Tafsīr Qur'ān Karīm. In order to uncover the ideological transformation of the Nusantara interpretation in this study, the hermeneutic method is used. The research results indicate that there are several tafsīr traditions contained in Tafsīr Qur'ān Karīm, including the knowledge tradition of interpretation, where Mahmud Yunus adopted Mustafa al-Maraghi's thoughts while studying at al-Azhar in Cairo, Egypt. Also the tradition of social interpretation where Mahmud Yunus adopted the thoughts of Rasyid Ridha and Abduh. These traditions continue to develop up today, not even a few interpreters interpret the Qur'an with a scientific and social approach, such as Tafsīr al-Azhar by Hamka, Tafsīr al-Bayan by Hasbi Ashidiqi, Tafsīr al-Furqan by A Hasan, and tafsīr.

Impacts of biomass burning and photochemical processing on the light absorption of brown carbon in the southeastern Tibetan Plateau
Authors: Tian Jie , Wang Qiyuan , Ma Yongyong , Wang Jin , Han Yongming , Cao Junji
Published: February 2023

Abstract. Brown carbon (BrC) in the atmosphere can greatly
influence aerosol's radiative forcing over the Tibetan Plateau (TP) because
it has the non-negligible capacity of light absorption compared to black
carbon (BC); however, our understanding of optical properties, sources,
and atmospheric processes of BrC in this region remains limited. In this study,
a multiple-wavelength Aethalometer coupled with a quadrupole aerosol
chemical speciation monitor was deployed to investigate the highly time
resolved BrC in the submicron aerosol at the southeastern edge of the TP
during the pre-monsoon season. The results showed that BrC made
substantial contributions (20.0 %–40.2 %) to the light absorption of
submicron aerosol from 370 to 660 nm. Organic aerosol (OA), an alternative
to BrC, was split into a biomass burning OA (BBOA) with aging processes and a
photochemical-oxidation-processed oxygenated OA (po-OOA) by a hybrid
environmental receptor model analysis. Combined with the light absorption
coefficient of BrC (babs-BrC), the source-specific mass absorption cross
sections of BBOA (0.61–2.78 m2 g−1) and po-OOA (0.30–1.43 m2 g−1) at 370–660 nm were retrieved. On average,
babs-BrC from po-OOA (1.3–6.0 Mm−1) was comparable to that from
BBOA (1.3–6.0 Mm−1) at all wavelengths. The concentration-weighted
trajectory analysis showed that the most important potential source regions
for babs-BrC values from BBOA and po-OOA were located in northern
Myanmar and along the China–Myanmar border, indicating the cross-border
transport of BrC from Southeast Asia. A “simple forcing efficiency”
evaluation further illustrated the importance of the BrC radiative effect with
the high fractional radiative forcing by two OAs relative to BC (48.8 ± 15.5 %). This study highlights a significant influence of BrC of
biomass burning origin and secondary formation on climate change over the TP
region during the pre-monsoon season.

Abstract. In the Northern Hemisphere, the mid-6th century was one of the coldest
periods of the last 2000 years, which was initiated by volcanic eruptions in 536 and 540 CE. Here, we study the effect of this volcanic double event
on the climate and society in Scandinavia with a special focus on southern
Norway. Using an ensemble of Max Planck Institute Earth system model transient simulations
for 521–680 CE, temperature, precipitation, and atmospheric circulation
patterns are analyzed. The simulated cooling magnitude is used as input for
a growing degree day (GDD) model setup for three different study areas in
southern Norway, representative of typical meteorological and landscape
conditions. Pollen from bogs inside these study areas are analyzed at high
resolution (1–3 cm sample intervals) to give insights into the validity of the GDD model setup with regard to the volcanic climate impact on the
regional scale and to link the different data sets with the archeological
records. We find that after the 536 and 540 CE double event, a maximum surface air cooling of up to 3.5 ∘C during the mean growing season is simulated regionally for southern Norway. With a scenario cooling of 3 ∘C, the GDD model indicates crop failures were likely in our
northernmost and western study areas, while crops were more likely to mature in the southeastern study area. These results are in agreement with the pollen records from the respective areas. Archeological excavations show, however, a more complex pattern for the three areas with abandonment of farms and severe social impacts but also a continuation of occupation or a mix of those. Finally, we discuss the likely climatic and societal impacts of the 536 and 540 CE volcanic double event by synthesizing the new and available data sets for the whole Scandinavia.
Cell tracking of convective rainfall: sensitivity of climate-change signal to tracking algorithm and cell definition (Cell-TAO v1.0)
Authors: Meredith Edmund P. , Ulbrich Uwe , Rust Henning W.
Published: February 2023

Abstract. Lagrangian analysis of convective precipitation involves identifying convective cells (“objects”) and tracking them through space and time. The Lagrangian approach helps to gain insight into the physical properties and impacts of convective cells and, in particular, how these may respond to climate change. Lagrangian analysis requires both a fixed definition of what constitutes a convective object and a reliable tracking algorithm. Whether the climate-change signals of various object properties are sensitive to the choice of tracking algorithm or to how a convective object is defined has received little attention. Here we perform ensemble pseudo-global-warming experiments at a convection-permitting resolution to test this question. Using two conceptually different tracking algorithms, Lagrangian analysis is systematically repeated with different thresholds for defining a convective object, namely minimum values for object area, intensity and lifetime. It is found that the threshold criteria for identifying a convective object can have a strong and statistically significant impact on the magnitude of the climate-change signal, for all analysed object properties. The tracking method, meanwhile, has no impact on the climate-change signal as long as the precipitation data have a sufficiently high temporal resolution: in general, the lower the minimum permitted object size is, the higher the precipitation data's temporal resolution must be. For the case considered in our study, these insights reveal that irrespective of the tracking method, projected changes in the characteristics of convective rainfall vary considerably between cells of differing intensity, area and lifetime.

global burned areas and have strong connection to local climate for
sub-seasonal to seasonal wildfire dynamics. However, representation of the
wildfire–climate relationship remains challenging due to spatiotemporally
heterogenous responses of wildfires to climate variability and human
influences. Here, we developed an interpretable machine learning (ML) fire
model (AttentionFire_v1.0) to resolve the complex controls of
climate and human activities on burned areas and to better predict burned
areas over ASA regions. Our ML fire model substantially improved
predictability of burned areas for both spatial and temporal dynamics
compared with five commonly used machine learning models. More importantly,
the model revealed strong time-lagged control from climate wetness on the
burned areas. The model also predicted that, under a high-emission future climate scenario, the recently observed declines in burned area will reverse
in South America in the near future due to climate changes. Our study
provides a reliable and interpretable fire model and highlights the importance
of lagged wildfire–climate relationships in historical and future
predictions.

Abstract. Earth system models (ESMs) integrate previously separate models of the ocean, atmosphere and vegetation into one comprehensive modelling system enabling the investigation of interactions between different components of the Earth system. Global isoprene and monoterpene emissions from terrestrial vegetation, which represent the most important source of volatile organic compounds (VOCs) in the Earth system, need to be included in global and regional chemical transport models given their major chemical impacts on the atmosphere. Due to the feedback of vegetation activity involving interactions with weather and climate, a coupled modelling system between vegetation and atmospheric chemistry is recommended to address the fate of biogenic volatile organic compounds (BVOCs). In this work, further development in linking LPJ-GUESS, a global dynamic vegetation model, to the atmospheric-chemistry-enabled atmosphere–ocean general circulation model EMAC is presented. New parameterisations are included to calculate the foliar density and leaf area density (LAD) distribution from LPJ-GUESS information. The new vegetation parameters are combined with existing LPJ-GUESS output (i.e. leaf area index and cover fractions) and used in empirically based BVOC modules in EMAC. Estimates of terrestrial BVOC emissions from EMAC's submodels ONEMIS and MEGAN are evaluated using (1) prescribed climatological vegetation boundary conditions at the land–atmosphere interface and (2) dynamic vegetation states calculated in LPJ-GUESS (replacing the “offline” vegetation inputs). LPJ-GUESS-driven global emission estimates for isoprene and monoterpenes from the submodel ONEMIS were 546 and 102 Tg yr−1, respectively. MEGAN determines 657 and 55 Tg of isoprene and monoterpene emissions annually. The new vegetation-sensitive BVOC fluxes in EMAC are in good agreement with emissions from the semi-process-based module in LPJ-GUESS. The new coupled system is used to evaluate the temperature and vegetation sensitivity of BVOC fluxes in doubling CO2 scenarios. This work provides evidence that the new coupled model yields suitable estimates for global BVOC emissions that are responsive to vegetation dynamics. It is concluded that the proposed model set-up is useful for studying land–biosphere–atmosphere interactions in the Earth system.
A feasibility and dynamic performance analysis of hydromechanical hybrid power transmission technology for wind turbines
Authors: Kumar Dharmendra , Mahato Anil C.
Published: February 2023

Abstract. A multi-body dynamical model of a wind turbine power generation system (WTPGS) based on hydromechanical hybrid power
transmission (HMHPT) technology is developed and simulated to overcome the
individual drawbacks of the gear train and hydrostatic power
transmission (HPT) system. The HMHPT is a hybrid concept of a single-stage
planetary gear train (SSPGT) and a typical HPT. The input shaft of the SSPGT is coupled with the turbine rotor, whereas the output shaft of the SSPGT is coupled with the shaft of a hydraulic pump. The hydraulic pump supplies flow
to the hydro-motor, and its shaft is coupled with the generator. An existing
turbine blade model of 750 kW based wind turbine is used for further
development and analysis of the HMHPT. The simulation responses indicate
that the power generation and the control potential both have been
improved using the HMHPT in a wind turbine. Moreover, the influence on
the motor power generation due to variations of pump and motor leakages is
addressed. Additionally, it is found that if the order of the SSPGT and the
HPT are swapped in the proposed HMHPT, then the settling time, maximum
overshoot, and rise time of the system responses are increased. As a result,
the controllability of the system is decreased.

Abstract. Consecutive ML 7.0 submarine earthquakes occurred offshore of the Hengchun Peninsula, Taiwan, on 26 December 2006. A small tsunami was generated and recorded at tide gauge stations. This important event attracted public interest, as it was generated by an earthquake doublet and produced a tsunami risk for Taiwan. This study analyzed tide gauge tsunami waveforms and numerical simulations to understand the source characteristics
and resulting behaviors of tsunamis. The maximum wave heights at the three
nearest stations were 0.08 m (Kaohsiung), 0.12 m (Dongkung), and 0.3 m
(Houbihu), and only Houbihu recorded the first wave crest as the largest.
The tsunami duration was 3.9 h at Dongkung and over 6 h at Kaohsiung and
Houbihu. Spectral analyses detected dominant periodic components of spectral peaks on the tsunami waveforms. The period band from 13.6–23.1 min was identified as the tsunami source spectrum, and the approximate fault area for the consecutive tsunamis was estimated to be 800 km2, with central fault depths of 20 km (first earthquake, Mw 7.0) and 33 km (second earthquake, Mw 6.9). The focal mechanisms of the first earthquake, with
a strike of 319∘, dip of 69∘, and rake of
−102∘, and the second earthquake, with a strike of 151∘, dip of 48∘, and rake of 0∘, could successfully
reproduce the observed tsunami waveforms. Numerical simulations suggested
that the tsunami waves were coastally trapped on the south coast of Taiwan
during the tsunami's passage. The trapped waves propagated along the coast
as edge waves, which repeatedly reflected and refracted among the shelves,
interfered with incoming incident wave, and resonated with the fundamental
modes of the shelves, amplifying and continuing the tsunami wave
oscillation. These results elucidated the generation and consequential
behaviors of the 2006 tsunami in southern Taiwan, contributing essential
information for tsunami warning and coastal emergency response in Taiwan to
reduce disaster risk.
Evolution of the dynamics, area, and ice production of the Amundsen Sea Polynya, Antarctica, 2016–2021

Abstract. Polynyas are key sites of ice production during the winter and are
important sites of biological activity and carbon sequestration during the
summer. The Amundsen Sea Polynya (ASP) is the fourth largest Antarctic
polynya, has recorded the highest primary productivity, and lies in an
embayment of key oceanographic significance. However, knowledge of its
dynamics, and of sub-annual variations in its area and ice production, is
limited. In this study we primarily utilize Sentinel-1 synthetic aperture radar (SAR) imagery, sea ice concentration products, and climate reanalysis data, along with bathymetric
data, to analyze the ASP over the period November 2016–March 2021.
Specifically, we analyze (i) qualitative changes in the ASP's
characteristics and dynamics, as well as quantitative changes in (ii) summer
polynya area, and (iii) winter polynya area and ice production. From our
analysis of SAR imagery we find that ice produced by the ASP becomes stuck
in the vicinity of the polynya and sometimes flows back into the polynya,
contributing to its closure and limiting further ice production. The polynya
forms westward off a persistent chain of grounded icebergs that are located
at the site of a bathymetric high. Grounded icebergs also influence the
outflow of ice and facilitate the formation of a “secondary polynya” at
times. Additionally, unlike some polynyas, ice produced by the polynya flows
westward after formation, along the coast and into the neighboring sea
sector. During the summer and early winter, broader regional sea ice
conditions can play an important role in the polynya. The polynya opens in
all summers, but record-low sea ice conditions in 2016/17 cause it to become
part of the open ocean. During the winter, an average of 78 % of ice
production occurs in April–May and September–October, but large polynya
events often associated with high, southeasterly or easterly winds can
cause ice production throughout the winter. While passive microwave data or
daily sea ice concentration products remain key for analyzing variations in
polynya area and ice production, we find that the ability to directly
observe and qualitatively analyze the polynya at a high temporal and spatial
resolution with Sentinel-1 imagery provides important insights about the
behavior of the polynya that are not possible with those datasets.
