The study of the marine microbiome is essential to understanding the health of our oceans and their impact on the planet. These microorganisms play a crucial role in the regulation of biogeochemical cycles, oxygen production, degradation of pollutants and the marine food chain. In addition, the marine microbiome influences the global climate and is a valuable resource for biotechnology and medicine. Investigating this microscopic world helps us protect our marine ecosystems and address urgent environmental challenges. DNA analysis through techniques such as amplicon sequencing (metabarcoding) allows the identification of both prokaryotic and eukaryotic microbial species in water samples. Metagenomics, on the other hand, gives us the ability to sequence all the genes present in the microbiome, providing information about gene abundances involved in metabolic pathways (profiles functional) and at different taxonomic levels (taxonomic profiles). Ocean Sampling Day (OSD) is a global scientific campaign that aims to analyze marine biodiversity and microbial function using molecular sequencing techniques. This dataset contains 2 occurrences that were taken in Puerto Colombia and Barranquilla the 9th of september 2023, both are identified up to domain Eukarya and Prokaryota.
Sponge occurrence and associated species and habitat descriptions derived from the 2021 and 2022 SCUBA diving surveys in the Eastern Shore Islands Area of Interest, Nova Scotia.
Funded under DFO's Marine Conservation Targets Program in partnership with the Huntsman Marine Science Centre (HMSC), this diver-based imagery and sample collection benthic survey documents the occurrence of sponges at 42 dive sites in the Eastern Shore Islands (ESI) Area of Interest (AOI, ~2089 km2) off the Atlantic coast of Nova Scotia, Canada from dive surveys conducted in summer 2021 and 2022. Water quality, species occurrences and counts, habitat, slope, and substrate characteristics were catalogued through diver log sheets, camera imagery, specimen vouchers, and high-resolution bathymetric data. A total of 54 dives to depths from 11 to 33 m (below sea level), collecting up to 147 still images, one-hour of video, and 17 specimen samples per site, resulted in 220 observations for 27 different sponge taxa. This included three new records for Canada (Hymedesmia stellifera, Plocamionida arndti, Hymedesmia jecusculum) and a range extension for a species new to science (Crellomima mehqisinpekonuta) which was recently described from the Bay of Fundy. There were also four species which may seem to be new to science (Halichondria sp., Hymedesmia sp., Protosuberires sp., and Sphaerotylus sp.). Sponges were found to occupy a diversity of micro-habitats, often several different ones in proximity. A total of eight distinct habitat classes were defined, based on varying abundances and diversity of sponges and associated benthic species. These are likely widely distributed among the many complex submerged seabed features within this AOI. Collected specimens were preserved and are stored at the Atlantic Reference Centre (ARC) in St. Andrew's, New Brunswick.
Unveiling the UNESCO Biosphere Reserve of the Berlengas Archipelago in Portugal as a Hotspot of Fish Species Using eDNA Metabarcoding and the Collaboration of Fishing Crews.
This study aims to evaluate the spatiotemporal diversity of fish using 12S rRNA gene eDNA metabarcoding sequencing in the Berlengas archipelago and compare two seawater eDNA sampling sources: samples collected by fishermen during their activities and those collected by our research team. The results indicated that autumn presented the highest diversity and that the area around Berlenga Island was the richest area, increasing biodiversity across the region.
DFO Arctic Region Biodiversity of the Benthic Infauna Box Core Survey from CBS-MEA program (2021-2023)
This resource documents a dataset of infauna occurrences collected from 2021 to 2023 during the Canadian Beaufort Sea Marine Ecosystem Assessment (CBS-MEA) conducted by the Department of Fisheries and Oceans (DFO). This scientific program focuses on the integration of oceanography, food web linkages, physical-biological couplings, and spatial and interannual variabilities.The program also aims to expand the baseline coverage of species diversity, abundances, and habitat associations in previously unstudied areas of the Beaufort Sea and Western Canadian Archipelago. Endobenthic invertebrates were identified from catches collected with a 50 x 50 cm box corer. //Cette ressource documente un jeu de données sur les occurrences d'endofaune collectées de 2021 à 2023 lors de l'évaluation environnementale marine de la mer de Beaufort canadienne (CBS-MEA) menée par Pêches et Océans Canada (MPO). Le programme CBS-MEA se concentre sur l'intégration de l'océanographie, des liens dans le réseau alimentaire, des couplages physico-biologiques et des variabilités spatiales et interannuelles. Le programme vise également à élargir la couverture de référence de la diversité des espèces, des abondances et des associations avec les habitats dans des zones de la mer de Beaufort et de l'archipel canadien de l'Ouest précédemment non étudiées. Les invertébrés endobenthiques ont été identifiés à partir des prises collectées par un carottier à boîte de 50 x 50 cm.
Two new species in the genus Petta from deep waters of southeastern Australia, RV Investigator voyage IN2017_V03 (2017)
Petta Malmgren, 1866 is a small and poorly known genus of the annelid family Pectinariidae Quatrefages, 1866. Prior to this study, the genus comprised four species. The authors have revised the genus by re-examining the types and providing updated illustrated re-descriptions of its species, except for P. assimilis of which the type material has been lost. Two species P. investigatoris n. sp. and P. williamsonae n. sp. are described from deep water off the coast of southeastern Australia and represent the first records of this genus in Australian waters. These two species were collected from the RV Investigator voyage IN2017_V03 - see IN2017_V03 for voyage details, maps, other data and publications. If this data has been used in any products, please acknowledge with the following: We acknowledge the use of the CSIRO Marine National Facility (https://ror.org/01mae9353) in undertaking this research.
Metabarcoding of Benthic Marine Communities in Nova Scotia and New Brunswick
To monitor marine invasive species distribution and broad taxonomic diversity in the subtidal fauna and flora of the DFO Maritimes region, metabarcoding of eDNA samples was performed at a total of 49 sites between 2021-2022. For each site, three 1-L amber bottles of seawater collected from ~1m above the benthos at each site was filtered with Sterivex 0.22-µm filters prior to DNA extraction with a Qiagen DNEasy Power Water Kit and sequencing with an Illumina NovaSeqtm6000 instrument (primers are included in metadata). Raw paired-end reads were merged with NGmerge v0.3 and denoised with DnoisE v1.4.1 (DnoisE settings are included in the metadata). Singletons were removed and remaining sequences were assigned to species-level by BLAST against a local copy of the nr/nt database (downloaded Nov 2023).
Use cases
State of knowledge on marine connectivity gathered by migratory marine species
ABNJ connectivity marine species management telemetry tracking
Advancements in technology have improved our knowledge of how different areas of the ocean are connected by the movement of migratory and mobile marine species. This information is vital to inform area-based management and conservation efforts. The authors of this study, led by the OBIS-SEAMAP node, performed a literature review of 25 years of accessible connectivity data for 173 marine mammal, fish, sea turtle, and seabird species to shed light on the current state of knowledge. They found telemetry methods are the most effective tool for demonstrating connectivity, but that significant gaps and obstacles remain in this field of research.
