Abstract. Even though oceans cover the majority of the Earth, most aerosol measurements are from continental sites. We measured aerosol particle number size distribution at Baring Head, in coastal New Zealand, over a total period of 10 months to study aerosol properties and new particle formation, with a special focus on aerosol formation in open-ocean air masses. Particle concentrations were higher in land-influenced air compared to clean marine air in all size classes, from sub-10 nm to cloud condensation nuclei sizes. When classifying the particle number size distributions with traditional methods designed for continental sites, new particle formation was observed at the station throughout the year with an average event frequency of 23 %. While most of these traditional event days had some land influence, we also observed particle growth starting from nucleation mode in 16 % of the data in clean marine air, and at least part of this growth was connected to nucleation in the marine boundary layer. Sub-10 nm particles accounted for 29 % of the total aerosol number concentration of particles larger than 1 nm in marine air during the spring. This shows that nucleation in marine air is frequent enough to influence the total particle concentration. Particle formation in land-influenced air was more intense and had on average higher growth rates than what was found for marine air. Particle formation and primary emissions increased particle number concentrations as a function of time spent over land during the first 1–2 d. After this, nucleation seems to start getting suppressed by the pre-existing particle population, but accumulation mode particle concentration keeps increasing, likely due to primary particle emissions. Further work showed that traditional NPF events were favoured by sunny conditions with low relative humidity and wind speeds. In marine air, formation of sub-10 nm particles was favoured by low temperatures, relative humidity, and wind speeds and could happen even during the night. Our future work will study the mechanisms responsible for particle formation at Baring Head with a focus on different chemical precursor species. This study sheds light on both new particle formation in open-ocean air masses coming from the Southern Ocean and local aerosol properties in New Zealand.
Climatic variation drives loss and restructuring of carbon and nitrogen in boreal forest wildfire

Published: May 2022

Abstract. The boreal forest landscape covers approximately 10 % of the earth's land area and accounts for almost 30 % of the global annual terrestrial sink of carbon (C). Increased emissions due to climate-change-amplified fire frequency, size, and intensity threaten to remove elements such as C and nitrogen (N) from forest soil and vegetation at rates faster than they accumulate. This may result in large areas within the region becoming a net source of greenhouse gases, creating a positive feedback loop with a changing climate. Meter-scale estimates of area-normalized fire emissions are limited in Eurasian boreal forests, and knowledge of their relation to climate and ecosystem properties is sparse. This study sampled 50 separate Swedish wildfires, which occurred during an extreme fire season in 2018, providing quantitative estimates of C and N loss due to fire along a climate gradient. Mean annual precipitation had strong positive effects on total fuel, which was the strongest driver for increasing C and N losses. Mean annual temperature (MAT) influenced both pre- and postfire organic layer soil bulk density and C : N ratio, which had mixed effects on C and N losses. Significant fire-induced loss of C estimated in the 50 plots was comparable to estimates in similar Eurasian forests but approximately a quarter of those found in typically more intense North American boreal wildfires. N loss was insignificant, though a large amount of fire-affected fuel was converted to a low C : N surface layer of char in proportion to increased MAT. These results reveal large quantitative differences in C and N losses between global regions and their linkage to the broad range of climate conditions within Fennoscandia. A need exists to better incorporate these factors into models to improve estimates of global emissions of C and N due to fire in future climate scenarios. Additionally, this study demonstrated a linkage between climate and the extent of charring of soil fuel and discusses its potential for altering C and N dynamics in postfire recovery.
ECOSMO II(CHL): a marine biogeochemical model for the North Atlantic and the Arctic
Authors: Yumruktepe Veli Çağlar , Samuelsen Annette , Daewel Ute 
Published: May 2022

Abstract. ECOSMO II is a fully coupled bio-physical model of 3D hydrodynamics with an intermediate-complexity NPZD (nutrient, phytoplankton, zooplankton, detritus) type biology including sediment-water column exchange processes originally formulated for the North Sea and Baltic Sea. Here we present an updated version of the model incorporating chlorophyll a as a prognostic state variable: ECOSMO II(CHL). The version presented here is online coupled to the HYCOM ocean model. The model is intended to be used for regional configurations for the North Atlantic and the Arctic incorporating coarse to high spatial resolutions for hind-casting and operational purposes. We provide the full descriptions of the changes in ECOSMO II(CHL) from ECOSMO II and provide the evaluation for the inorganic nutrients and chlorophyll a variables, present the modelled biogeochemistry of the Nordic Seas and the Arctic, and experiment on various parameterization sets as use cases targeting chlorophyll a dynamics. We document the performance of each parameter set objectively analysing the experiments against in situ, satellite and climatology data. The model evaluations for
each experiment demonstrated that the simulations are consistent with the
large-scale climatological nutrient setting and are capable of representing
regional and seasonal changes. Explicitly resolving chlorophyll a allows for more dynamic seasonal and vertical variations in phytoplankton biomass to chlorophyll a ratio and improves model chlorophyll a performance near the surface. Through experimenting with the model performance, we document the general biogeochemisty of the Nordic Seas and the Arctic. The Norwegian and Barents seas primary production show distinct seasonal patterns with a
pronounced spring bloom dominated by diatoms and low biomass during winter
months. The Norwegian Sea annual primary production is around double that of
the Barents Sea while also having an earlier spring bloom.

Abstract. Planktonic food webs were studied contemporaneously in a mesoscale cyclonic (upwelling, ∼ 13 months old) and an anticyclonic (downwelling,
∼ 2 months old) eddy as well as in an uninfluenced background situation in the oligotrophic southeastern Mediterranean Sea (SEMS) during
late summer 2018. We show that integrated nutrient concentrations were higher in the cyclone compared to the anticyclone or the background
stations by 2–13-fold. Concurrently, Synechococcus and Prochlorococcus were the dominant autotrophs abundance-wise in the
oligotrophic anticyclone (∼ 300 × 1010 cells m−2). In the cyclone, functional groups such as dinoflagellates,
Prymnesiophyceae and Ochrophyta contributed substantially to the total phytoplankton abundance (∼ 14 × 1010 cells m−2), which was ∼ 65 % lower at the anticyclone and background stations (∼ 5 × 1010 cells m−2). Primary production
was highest in the cyclonic eddy (191 mgCm-2d-1) and 2–5-fold lower outside the eddy area. Heterotrophic prokaryotic
cell-specific activity was highest in the cyclone (∼ 10 fgCcell-1d-1), while the least productive cells were found in the
anticyclone (4 fgCcell-1d-1). Total zooplankton biomass in the upper 300 m was 10-fold higher in the cyclone compared
with the anticyclone or background stations (1337 vs. 112–133 mg C m−2, respectively). Copepod diversity was much higher in the
cyclone (44 species), compared to the anticyclone (6 small-size species). Our results highlight that cyclonic and anticyclonic eddies show
significantly different community structure and food-web dynamics in oligotrophic environments, with cyclones representing productive oases in the
marine desert of the SEMS.

Published: May 2022

Objectives Excessive mobile phone use contributes to distracted driving, may increase risk for automobile accidents, and a minority of mobile phone users exhibit behaviors consistent with technological addiction. The purpose of this study was to determine whether cell phone beliefs and behaviors could be changed by a brief educational encounter. The Theory of Reasoned Action provided a lens for viewing attitudes and behavior. Methods A one-week pre-post design with a thirty-day follow-up was used with participants (N = 215, 67.0% female, age = 20.0 + 1.6) assigned to a peer-led intervention or comparison group. The intervention included cell phone educational materials regarding the potential for negative health effects of mobile phone use. A short index of cell phone behavior was developed which showed good internal consistency with a Cronbach’s α of .81. Results The intervention group “agreed” or “strongly-agreed” more than the comparison group on five of the seven areas of cell phone beliefs and behaviors ( P < 0.05, item Cohen’s d = .32 to .47, total d = .50) at one week following receipt of educational materials. Conclusions We conclude that attitudes and behaviors regarding mobile phones are malleable and susceptible to change in young adults following a brief psychoeducational intervention.
Fatal Coma Secondary to Acute Onset of Hyperammonemia in a Non-Cirrhotic Adult Male Secondary to a Urea Cycle Enzyme Deficiency—a Rare Disease Case Report
Authors: Sonier Clinton , Owens Micaela , Khurana Sandeep , Thakur Lokendra 
Published: May 2022

Introduction Acute hyperammonemia in adult patients without liver disease is uncommon. Other etiologies are broad and can be difficult to rule out quickly. Urea cycle disorders such as ornithine transcarbamylase (OTC) deficiency are rare and often present in children. Adult-onset cases are rarer. This makes recognizing and treating late-onset urea cycle disorders challenging in the acute setting. Case Report We present the case of a 56-year-old male with a history of early onset coronary artery disease, chronic back pain, and heavy tobacco use who was found unconscious at home by a neighbor. He was found to have toxic levels of serum ammonia during further evaluation in the emergency department. Laboratory testing confirmed a diagnosis of OTC deficiency. Genetic analysis further showed a c.-106C>A variant of the OTC gene. Conclusion Although extremely rare, late-onset urea cycle disorders should be considered when patients present with altered mental status with hyperammonemia of unknown etiology. Furthermore, this case adds evidence that the c.-106C>A OTC gene variant has pathogenic significance.

Published: May 2022

Nigeria implemented a National Health Insurance Scheme (NHIS) in 2005, introducing monumental changes to the health care delivery system. This study assessed physicians’ understanding of the objectives of the NHIS as well as their perceptions of the scheme, to identify their level of acceptance and support of the health policy reform. A convenient sample of 134 physicians residing in South-East Nigeria were surveyed via a self-administered questionnaire. Descriptive statistics were used to summarize study data. Aggregate knowledge scores regarding health insurance and the NHIS objectives were assessed. Measures of consensus (Cns) of physicians’ perceptions of the health reform were also obtained. Study results show a high level of awareness and support for the NHIS among participants. However, there were deviations between awareness of the NHIS and knowledge of the program’s objectives. Aggregate knowledge scores differed significantly by age group, length of years of practice, place of employment and location. Further, consensus measures of physician’s perceptions of NHIS (Cns index = 0.69) and the introduction of Health Maintenance Organizations (HMOs) as intermediary operators of the scheme (Cns index = 0.68) were positive and considered strong while perceptions on associations between HMOs and corruption in the country was moderate (Cns index = 0.56) and slightly negative. This study demonstrates physicians’ support for the NHIS program in Nigeria and an acceptance of changes implemented with the health policy reform. Knowledge gaps were identified, highlighting the need forincreased awareness of the reform and its objectives.

Published: May 2022

To evaluate the morphological and nutritional variability among six lablab bean (Lablab purpureusL.) genotypes, a study was carried out at Sylhet Agricultural University, Bangladesh and at Bangladesh Agricultural Research Institute (BARI) during mid-July 2014 to mid-March 2015. Significant morphological variations were noted in both seedling and vegetative stages in their growth. In addition, there were three distinct flower and flower wings color viz. white in SB003; violet in SB010, Rupvan, Auto, and Kanchan; and light violet in SB011 were noted among the genotypes. Further, 8 or 9 layers of flower wings were observed among the genotypes and the inflorescence length varied from 46.40 cm (SB011) to 42.40 cm (SB010). Considering the pod characteristics, pod length and breadth varied from 14.13 cm (SB011) to 8.13 cm(SB010), and 2.68 cm (Auto) to 2.43 cm (SB010), respectively. Significant variations were also noted for pod yield characteristics. The genotype of Kanchan had the highest number of pod/plant (202.7), whereas Auto had the highest pod yield (23.05 t/ha) followed by Kanchan (19.26 t/ha).The study also revealed that pod yield (t/ha) was positively correlated with the number of pods/plant (0.71), pod weight/plant (1.00), individual pod weight (0.65) and pod yield/decimal (1.00) among the genotypes. Furthermore, significant variations were also noted for the nutrient compositions among the genotypes. The analytical experiment shows that Auto had the highest proportion of Cu (15.28 ppm), Fe (122.22 ppm), Mn (40.74 ppm), B (60.60 ppm), S (0.158 %) and Ca (1.67%). In contrast, the genotype of SB003 had the highest amount of Zn (61.86 ppm) and SB011 had Mg (785 %) content. Therefore, the genotypes of Auto and Kanchan would be recommended for cultivation in the Sylhet region of Bangladesh.
