Seasonal Influence of the Island Mass Effect on Coastal Nutrient Dynamics and Phytoplankton Communities in Guadeloupe, a Tropical Volcanic Island (French West Indies)

Moreau Emma, Boye Marie, Pascal Pierre-Yves, Dessert Céline, Messié Monique

This repository contains raw data from flow cytometry, diagnostic pigments, and macro- and micro-nutrient measurements collected in the Caribbean Sea and the Atlantic Ocean, around Basse-Terre Island. Concentrations of macro- and micro-nutrients and anions are also provided for six rivers sampled from upstream to downstream in southern Basse-Terre. Additionally, data on particulate organic carbon and diagnostic pigments obtained during sediment i [...]

Phytoplankton Pigment Time Series from SO RadeMicro at Coastal Station Point B, Bay of Villefranche-sur-Mer, Ligurian Sea, NW Mediterranean

Pedrotti Maria Luiza, Mousseau Laure, Franck Petit, Ornella Passafiume, Hortense de Lary

The Bay of Villefranche-sur-Mer is 2 miles long and 0.8 miles wide, characterized by great depth (> 300 m at its mouth) and the absence of a continental shelf. This site, considered oligotrophic to mesotrophic, is located in a heavily urbanized area, subject to seasonal anthropogenic influences (cruise ships, intense yacht traffic, tourism). Thanks to the absence of a continental shelf and the northerly current, organisms living offshore reach th [...]

Target tracking in multibeam water-column images based on acoustic simulation of beam forming artifacts – video results

Perret Tymea, Le Chenadec Gilles, Gaillot Arnaud, Ladroit Yoann, Dupré Stéphanie

Multibeam echosounders have revolutionized underwater exploration, enabling the study of biological and geophysical phenomena such as fish distribution and gas venting. We employed automated deep-learning methods to analyze the large volume of water-column data, thus obtaining a big database of water-column echoes of different types. The subsequent objective is to ascertain the relationships between these echoes. Consequently, it is imperative to [...]

Trophic ecology and nutritional status of northern shrimp in Canada's sub-Arctic

Yunda-Guarin Gustavo, Atchison Sheila, Baker Krista, Cyr Frédéric, Parrish Christopher

In the Northwest Atlantic, Pandalus borealis (northern shrimp) serve as key mid-trophic consumers and prey for higher-trophic predators, including commercially important fish species. However, the impact of changing environmental conditions on trophic interactions and lipid storage in sub-Arctic ecosystems is not well understood. We employed biochemical tracers (fatty acids and stable isotopes) to investigate the trophic ecology and stage-specifi [...]

CTD and ADCP data collected during the cruise FARDWO CC1

Sanchez-Vidal Anna, Amblàs David, Arjona-Camas Marta, Durrieu de Madron Xavier, Calafat Antoni

CTD and ADCP obtained during the FARDWO-CCC1 Cruise, onboard the R/V Garcia del Cid. The aim of the cruise was to characterise the physical and biogeochemical characteristics of the dense water overflow in the Cap de Creus canyon as a part of the FARDWO project (Far-reaching impacts of dense water overflows in the North Atlantic Ocean and the Mediterranean Sea, PID2020-114322RB-I00, funded by MICIU/AEI /10.13039/501100011033). Data includes two h [...]

Phytoplankton incubations under Patagonian dust input and environmental changes in the Southern Ocean

Demasy Clément, Boye Marie, Delisée Ambroise, Maguer Jean-François, Thyssen Melilotus

This repository contains raw data from flow cytometry, diagnostic pigments, and particulate organic carbon and nitrogen analyses, collected during phytoplankton incubation experiments in the Southern Ocean in February 2022 (Indian section). One incubation was conducted in the Polar Frontal Zone and the other in a High-Nutrient, Low-Chlorophyll (HNLC) region. These experiments were carried out under various treatments, including the addition of Pa [...]
