Bathymetric distribution and temporal trends of macrobenthic communities of the continental shelf of Heraklion Bay (Crete-Greece)

This dataset includes species composition and abundances of macrobenthic faunal communities along three transects of Heraklion Bay (H2, H5, H7). The H2 transect is located in the wider marine area of the wastewater treatment plant of Heraklion city. Sampling was carried out during three different sampling surveys and periods — June 2010, June 2015, and August 2024 — at different depths (10, 20, 30, 40, 50, 100 and 200 m) along the soft-bottom continental shelf, as part of different research projects (MARBEFES, Marine Biology, Biotechnology - Aquaculture, monitoring program). A detailed comparison of species composition and abundance of macrobenthic faunal diversity among different depths and sampling periods is given, thus contributing to understanding the spatial and temporal trends and changes due to multiple environmental and human-induced stress.
ARMS-MBON data on long-term monitoring of hard-bottom communities: COI results from 2020-2022

ARMS-MBON is a network of more than 25 partners who deploy Autonomous Reef Monitoring Structures (ARMS) settlement units in the vicinity of marine stations and Long-term Ecological Research sites in European coastal waters and Ant/arctica. After a few months the units are brought up, and visual, photographic, and genetic assessments are made of the lifeforms that settled on them. The collected data are published (see the related datasets and GitHub links listed in this record) and the omics data analysed. In this record we include the outputs of our analysis of the COI data from the 2020-2022 campaign. The analysis used the PEMA bioinformatics software, and the resulting taxonomics inventory has been turned into DwC format. In addition, all the PEMA inputs and outputs can be found on the ARMS-MBON GitHub site (see links in this record), and the subset of the sampling data to which these COI results are linked can also be found on the ARMS-MBON GitHub site.
Bathynomus giganteus de la Colección de Crustáceos del Museo de Historia Natural Marina de Colombia - Makuriwa

El Museo de Historia Natural Marina de Colombia (MHNMC) alberga la colección más importante de crustáceos marinos del país. Los ejemplares se han recolectado como producto de múltiples proyectos desarrollados tanto por el INVEMAR, como por investigadores externos y otras entidades. La recolección se ha hecho por medio de técnicas como el arrastre bentónico, uso de nasas y trampas. Uno de los crustáceos que hacen parte de la colección es el isópodo gigante Bathynomus giganteus. Este organismo se encuentra en las aguas profundas del Atlántico tropical, incluyendo el Golfo de México, el Caribe y el Océano Índico (Shih 1972). Se desarrolla en áreas que oscilan entre los 300 y los 2000 m de profundidad (Obis 2021) y tiene una alimentación oportunista, centrada principalmente en carroña (Shih 1972). Se pueden identificar varios estadios de desarrollo en B. giganteus. El primer estadio, conocido como manca, se caracteriza por la falta de desarrollo del séptimo par de patas, en los individuos jóvenes, el séptimo par de patas está presente pero aún es pequeño, mientras que en los adultos se ha desarrollado por completo (Barradas-Ortiz, 2003). Las mancas de B. giganteus no pueden ser sexadas. En algunos casos, es posible identificar el sexo de los juveniles, y en los adultos, se distingue al macho por la presencia de penes en el esternito del séptimo pereionito, mientras que en la hembra se observan oosteguitos en la base de los pereiópodos I a V (Barradas-Ortiz, 2003). En otras especies de isópodos gigantes se ha reportado el consumo de macroalgas, estas últimas, son organismos clave en el secuestro del carbono en océanos. De ahí que, se espera que B. gigantes también cumpla este rol y por lo tanto resulta de interés para este proyecto. 

Los individuos de B. giganteus que reposan en la Colección de Crustáceos del MHNMC fueron recolectados en el Mar Caribe colombiano entre 2008-06-06 y 2019-01-11 y se encuentran almacenados en lotes que pueden contener uno o más individuos. El material fue consultado entre 2022-07-25 y 2022-08-03 para realizar el registro de medidas morfológicas a los ejemplares. El presente recurso contiene una extensión de datos que detalla las medidas de longitud, peso, sexo y estadío de desarrollo de 308 individuos pertenecientes a 46 lotes de la especie B. giganteus conservados dicha colección biológica.
Interacciones coral-césped, estructura de tallas de corales masivos y diversidad funcional de herbívoros como indicadores de estado de los arrecifes del complejo Islas Cayos de Bolívar, Reserva de Biosfera Seaflower

Se evaluó el estado del complejo arrecifal de Islas Cayos de Bolívar, Reserva de la Biosfera Seaflower. Para esto, se tomaron fotografías del sustrato, se seleccionaron entre 1 y 2 colonias de corales masivos morfológicamente contrastantes según su tipo de organización colonial (meandroide, plocoide y cerioide), que tuvieran bordes de interacción activa con céspedes algales y sobre estas interacciones, se estimó la diversidad y la redundancia funcional de herbívoros y macroalgas, se realizaron censos visuales de peces y macroinvertebrados en 3 puntos del arrecife utilizando el método de tipo estacionario y se realizaron anotaciones sobre la riqueza de especies/géneros, abundancia, tamaño y estadio de vida de los peces herbívoros pertenecientes a las familias Acanthuridae, Labridae-Scarinae, Ephippidae y Kyphosidae. Para el caso de los macroinvertebrados móviles, se buscaron ejemplares de Echinoideos y del crustáceo Maguimithrax sp.
Se identificó la presencia de 39 especies de corales pétreos y 4 especies de hidrocorales. Las especies que se encontraron en más del 50 % de las estaciones fueron: Agaricia agaricites, Favia fragum, Madracis decactis, Montastraea cavernosa, Orbicella annularis, Orbicella faveolata, Porites astraeoides, Porites porites, Pseudodiploria strigosa, Siderastrea siderea y Millepora alcicornis. Se encontraron 100 colonias afectadas por 9 signos asociados con enfermedades coralinas. Estos signos afectaron a 11 especies de corales pétreos y una especie de coral blando. Las especies que registraron mayor número de casos fueron O. annularis (31 %), S. siderea (21 %) y P. strigosa (19 %). Los herbívoros estuvieron representados por 16 especies de peces, pertenecientes a 3 familias (Acanthuridae = 3; Labridae = 9 y Kyphosidae = 4); 4 especies de erizos (Diadema antillarum, Echinometra lucunter, Echinometra viridis, Eucidaris tribuloides y Tripneustes ventricosus) y 2 especies de crustáceos (Percnon gibbesi y Maguimithrax spinosissimus).

Whale-Watching cetacean occurrences by Futurismo Azores Adventures from 2008 to 2018 off São Miguel (Azores)

Whale-watching vessels have become valuable platforms for cetacean data collection worldwide. In the Azores, a cetacean hotspot in the Atlantic, Futurismo Azores Adventures, a family-owned tourism company with whale-watching as its core business, has been collecting data regularly since 2008. The current dataset compiles observations of 20 cetacean species and 19 other species of marine megafauna, recorded by Futurismo Azores Adventures off São Miguel Island (Azores, Portugal) from 2008 to 2018. Data was collected during 4219 whale-watching commercial trips conducted daily and year-round. This information has been prepared for publication within the framework of the DTO-BioFlow project, which aims to enable a data flow into the EU Digital Twin Ocean.
Composition and morpho-functional traits of zooplankton swimmers and sinkers collected by -quot;Mooring Dirigibile Italia-quot; sediment trap

This dataset comprises zooplankton samples collected using sediment traps deployed at a depth of 87 meters at the “Mooring Dirigibile Italia” (MDI) site (78°54.815 N, 12°14.899 E) in the inner part of Kongsfjorden (Svalbard), near tidewater glacier fronts. As part of the KAIROS project, the dataset spans eight years (2014–2022) and has been curated to adhere to FAIR principles. The dataset underwent thorough data review, formatting, quality control, validation, and standardization. Furthermore, zooplankton data was integrated with oceanographic data (seawater temperature and salinity) collected synoptically at the same site.  Morpho-functional traits for the different taxa collected were also measured for campaign VIII and XIII to better characterize the zooplankton size structures.
Distribution records of Tunisian bryozoans reported in Northern Tunisian coasts since 2004

Tunisian bryozoans are poorly studied, their knowledge was based especially on some old works. An updated list counting 201 was conducted by d’Hondt -amp; Mascarell (2004) by adding to the previous literature data a total of 22 species. More recently, some studies carried out in northern Tunisia by Ayari et al. (2008; 2012a; 2012b; 2014 and 2022), resulted in the identification of 72 bryozoan species, among which 26 species were newly added to the Tunisian fauna.
The dataset of the Tunisian bryozoans reported by Ayari since 2004 groups those signalizations giving information about their distribution and habitats.
Abundance, biomass and size structure of the dusky grouper (Epinephelus marginatus) and the brown meagre (Sciaena umbra) according to protection status in the marine reserve of Scandola (Corsica, NW Mediterranean) in 2012 and 2018

This dataset gathers, total abundance, abundance per size class, total biomass and biomass per size class of two vulnerable fish species, the dusky grouper, Epinephelus marginatus (Lowe, 1834), and the brown meagre, Sciaena umbra Linaeus, 1758, recorded inside and outside the Marine Natural Reserve of Scandola (Corsica, NW Mediterranean) in 2012 and 2018. Fish were recorded by underwater visual censuses performed on belt transects (50 x 15 m) run parallel to the coast between 1 and 40 m depth at 13 sites according to three levels of protection status (integral reserve, buffer zone and unprotected zone). A total of 532 transects were performed in 2012 and 526 in 2018.
Heterobranquios observados en la Expedición Seaflower Isla Cayo Bolivar 2022 - Proyecto Colombia BIO

La infraclase Euthyneura (Heterobranchia: Mollusca) incluye especies que exhiben gran diversidad en formas, tamaños y coloraciones. En Colombia, es posible encontrar especies de este clado tanto en el Caribe como en el Pacífico, asociadas a diversos ecosistemas (e.g., arrecifales coralinos y rocosos). A pesar de la importancia que reviste el conocimiento de los invertebrados marinos asociados a un ecosistema, y en este caso particular a los moluscos de la infraclase Euthyneura, los estudios sobre este tipo de organismos son básicamente inexistentes en la región del Caribe insular colombiano. Por el contrario, estudios sobre los moluscos con concha en sitios cercanos al continente son más fáciles de encontrar. Con el objetivo de determinar la biodiversidad de Heterobranchia: Euthyneura, presente en los ecosistemas arrecifales submareales someros de la Isla Cayos de Bolívar, se realizaron muestreos usando la metodología ECORAPs a través de careteo y buceo libre en los rangos de profundidad de 0,20 a 35 m. Se encontraron 14 especies de babosas y liebres marinas que fueron fotografiadas e identificadas in situ y de las cuales se recolectaron algunos especímenes que fueron preservados en viales con etanol al 96%. Lo anterior, permitió obtener una lista de especies que permite ampliar los reportes previos y aportar al conocimiento y conservación del grupo, y generar un catálogo visual de las especies de Euthyneura asociadas a los ecosistemas arrecifales de la Isla Cayos de Bolívar en la Reserva de la Biosfera Seaflower.
Meiobenthic community in the Westerschelde estuary between 1977 and 1979

Data on quantitative aspects of the meiofauna community in the Westerschelde estuary such as density, biomass, diversity and community structure. The data were digitized by VLIZ from the original report: Van Damme, D.; Herman, R.; Sharma, Y.; Holvoet, M.; Martens, P. (1980). Benthic studies of the Southern Bight of the North Sea and its adjacent continental estuaries: Progress Report 2. Fluctuation of the meiobenthic communities in the Westerschelde estuary.
The meiofauna community of the Westerschelde estuary was examined along five transects over an one year period. All meiofaunal groups, excluding nematodes, occurred in very low numbers along the estuary, except at the salt marsh Saeftinghe, where they attain normal to high values. The average number of taxa decline from 4.3 at the mouth of the estuary at Vlissingen to 1.5 at Doel. Similar trends are observed for annual mean density.
Waterbird observations in Lake Victoria wetlands, south Kenya coast and Tana River dams (Kenya) in 1995

Count of observed waterbirds during a survey in Kenya in 1995. The data were digitized by VLIZ from the original report: Nasirwa, O.; Oyugi, J.; Jackson, C.; Lens, L.; Bennun, L.; Seys, J. (1995). Surveys of waterbirds in Kenya, 1995: Lake Victoria wetlands, south Kenya coast and Tana River dams. Centre for Biodiversity Research Reports: Ornithology, 20. National Museums of Kenya: Nairobi. 22 pp.
In February 1995, eight sites around Lake Victoria and beaches, reefs and creeks along the Kenyan coast from Vanga to Sabaki River mouth (around 220 km of shoreline, split into 15 sites) were surveyed and waterbirds counted. In March 1995, waterbirds were counted on the five large dams along the upper Tana River. These represent the first waterbird surveys for almost all of these sites. Five sites (Vanga Creek, Kilifi-Mida Beach, Malindi Marine Park, Sabaki River Mouth and Masinga Dam) qualify as Globally Important Bird Areas on the basis of their waterbird populations (and hence as potential Ramsar sites).
OCEAMM harbor porpoise sightings in the North Sea

In this study, systematic surveys were conducted to document the distribution of the harbor porpoise observed in the English Channel (North Sea, France).
Small cetaceans can use a variety of habitats and are generally wide-ranging. For this reason, extensive sighting surveys to assess their distribution, abundance, and habitat preference are needed. In this study, we conducted systematic surveys to document the distribution of the harbor porpoise observed in the English Channel (North Sea, France). The English Channel is an epicontinental sea. It constitutes a relatively narrow link between the Atlantic Ocean and the North Sea and is influenced by strong tides and freshwater inputs, which create well-mixed waters. The harbor porpoise is placed under Appendix II of the European Union Habitats Directive, and an assessment of his status and distribution in the English Channel, very exposed to human activities, is much needed to identify conservation and management strategies.

Therefore, we conducted surveys following a series of predetermined saw-tooth transect lines to study the distribution of the harbor porpoise (Phocoena phocoena). Boat transects were conducted using a Sealine Stateman 35, equipped with two 230 hp Volvo inboard engines at speed around 10 knots. Surveys were made as many days as possible throughout the season at sea state of Beaufort 3 or less, between March 2009 and September 2011.

For each animal sighting, the species, angle of sighting, the distance from the boat, the group size and composition, the general behavior and the swimming direction were recorded.

Long-Distance Movement of a Sei Whale in the North Atlantic, 2005

Long-distance migration for most species of baleen whales is poorly understood because of the practical difficulties and substantial expense involved in gathering relevant data. Presently, satellite tracking is the only method that delivers the necessary detail and quantitative data on movement patterns on far-ranging marine mammals. In this study, ARGOS satellite tags were deployed on North Atlantic sei whales (-lt;i-gt;Balaenoptera borealis-lt;/i-gt;) at the Azores Islands. The results show the largescale movement potential of North Atlantic sei whales from wintering grounds to highly productive potential feeding areas in the Labrador Sea.
Results: Data from one whale showed a cumulative 4,102 km movement from tagging at Faial Island in the Azores on 12 April 2005 via the Charlie Gibbs Fracture Zone (CGFZ) to the Labrador Sea where transmissions stopped on 7 June 2005. For a portion of the distance from CGFZ to the Labrador Sea, the whale moved in the prevailing direction of the surface current pattern. Erratic movement in five areas along the movement track indicates feeding behavior, particularly in the CGFZ. Original provider: Erik Olsen, Institute of Marine Research Dataset credits: Erik Olsen and Leif Nøttestad, Institute of Marine Research Purpose: The purpose of this study was to track sei whales from winter grounds off the Azores to summer feeding grounds in the North Atlantic Supplemental information: All location classes are visualized. There is a gap from location of tagging to first transmission.
