Shallow underwater hydrothermal systems are often overlooked despite their potential contribution to marine diversity and biogeochemistry. Over a decade after its eruption, the Tagoro submarine volcano continues to emit heat, reduced compounds, and nutrients into shallow waters, serving as a model system for studying the effects of diffuse hydrothermal fluids on surface microbial communities. The impact on both phytoplankton a...

Distributions of dissolved (DOM) and suspended (POM) organic matter, and their chromophoric (CDOM) and fluorescent (FDOM) fractions, are investigated at high resolution (< 10 km) in the Cape Verde Frontal Zone (CVFZ) during fall 2017. In the epipelagic layer (< 200 m), meso- and submesoscale structures (meanders, eddies) captured by the high resolution sampling dictate the tight coupling between physical and biogeochemical par...

We developed a new hindcast for storm surge at a 0.25° spatial scale for the whole New Zealand area using a statistical downscaling technique that links the mean local atmospheric conditions with the maximum storm surge levels at a daily scale. After validating the hindcast against sea level instrumental records from 17 tidal gauges around New Zealand, the same technique has been applied to obtain storm surge projections until...

The molecular composition of marine dissolved organic matter (DOM) is still poorly understood, particularly in the Mediterranean Sea. In this work, DOM from the open Mediterranean Sea and the adjacent Northeast Atlantic Ocean was isolated by solid‐phase extraction (SPE‐DOM) and molecularly characterized using Fourier‐transform ion cyclotron resonance mass spectrometry. We assessed the gradual reworking of the SPE‐DOM transport...
