De Nouméa à l’île Campbell, en passant par Paris port de mer et La Rochelle-Pallice : le voyage autour du monde de l’ingénieur hydrographe Jean-Jacques Anatole Bouquet de la Grye (1827-1909)

Cahiers François Viète
Jean-Jacques Anatole Bouquet de La Grye (1827-1909) graduated from the École polytechnique in 1847 with the rank of “ingénieur hydrographe”. He began his career surveying the coasts of the Island of Elba, Tuscany and then those of Loire-Atlantique.

Itinérances américaines et histoire(s) coloniale(s) dans l’oeuvre du navigateur Alessandro Malaspina

E-Spania, 2017
Après avoir rappelé le contexte de l’expédition Malaspina (1789-1794), nous étudierons, à travers l’écriture du témoignage, l’appréhension historique de l’empire espagnol et sa modélisation historico-littéraire dans le Viaje alrededor del mundo du ...

Organic Matter Stoichiometry Regulates the Continental Shelf Carbon Pump Efficiency of the Northwest European Shelf Seas

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Variations in the elemental C:N:P ratios of organic matter (OM) influence the coupling of carbon and nutrient cycles in the ocean. In this study, we assess the relevance of OM C:N:P stoichiometry for regional carbon cycling in the northwest European shelf seas (NWES).

A Comparative Study on the Irrigation Suitability of Kerala's Rivers Using Fuzzy AHP and Conventional Methods

Irrigation and Drainage, Volume 75, Issue 2, Page 815-839, April 2026.
ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

A Multi Tracer Approach Reveals Groundwater Residence Times and Dynamic Endmember Mixing in the Subterranean Estuary of a High Energy Beach

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Subterranean estuaries (STEs) under high‐energy conditions function as effective biogeochemical reactors, where waterbodies of varying physico‐chemical properties mix. Chemical reactions within the STE modulate the solute composition of groundwater discharging to the sea providing for example nutrients for plankton growth to coastal ecosystems.

Spatial Variability of Sea State in the German Bight and Influence of Offshore Wind Farms

Wind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT Offshore wind farms are growing worldwide and increase the source of renewable energy. However, as the extent and density of offshore wind farms increase, there is growing importance to understand the interactions with physical systems and the marine environment, in particular, the sea state.

Coupling large-spatial scale larval dispersal modelling with barcoding to refine the amphi-Atlantic connectivity hypothesis in deep-sea seep mussels

Frontiers in Marine Science, 2023
In highly fragmented and relatively stable cold-seep ecosystems, species are expected to exhibit high migration rates and long-distance dispersal of long-lived pelagic larvae to maintain genetic integrity over their range.

Heatwaves and a history of variability shape phytoplankton community thermal responses within one generation

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Predicting the effect of increased thermal unpredictability, for example in the shape of heatwaves on phytoplankton metabolic responses is ripe with challenges. While single genotypes in laboratory environments will respond to environmental fluctuations in predictable and repeatable ways, it is difficult to relate rapid evolutionary responses ...

Subsurface sediment properties and potential impacts of marine sand extraction on sand wave occurrence on the Netherlands Continental Shelf

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
This study reveals that a deeper sediment layer on the Netherlands Continental Shelf, which is exposed due to sand extraction, is generally finer and muddier than the previous surface layer. Additionally, the exposure of this layer will generally lead to a reduced occurrence of sand waves.
