Seasonal forecasting of subsurface marine heatwaves

Communications Earth & Environment, 2023
Marine heatwaves damage marine ecosystems and services, with effects identified mostly below the ocean surface. To create a truly user-relevant detection system, it is necessary to provide subsurface forecasts.

Toward linking ocean models to fish population dynamics [PDF]

, 2009
We discuss Lehodey et al.’s (2009) approach to linking ocean models to population dynamics of large marine predators, consider its benefits and limitations, and outline alternative approaches.

Weighing the ocean: Using a single mooring to measure changes in the mass of the ocean [PDF]

, 2012
Combining ocean and earth models, we show that there is a region in the central Pacific ocean where ocean bottom pressure is a direct measure of interannual changes in ocean mass, with a noise level for annual means below 3 mm water equivalent, and a ...

Impact of upstream variability on the Loop Current dynamics in numerical simulations of the Gulf of Mexico

Frontiers in Marine Science, 2023
The Loop Current (LC), which is the main mesoscale dynamic feature of the Gulf of Mexico (GoM), has a major impact on the circulation and its variability in the interior Gulf. The LC is a highly variable and dynamic feature. It changes shape from a short

Modelling the global coastal ocean [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008
Shelf and coastal seas are regions of exceptionally high biological productivity, high rates of biogeochemical cycling and immense socio-economic importance. They are, however, poorly represented by the present generation of Earth system models, both in terms of resolution and process representation.

The Rossby radius in the Arctic Ocean [PDF]

, 2014
The first (and second) baroclinic deformation (or Rossby) radii are presented north of ~60° N, focusing on deep basins and shelf seas in the high Arctic Ocean, the Nordic seas, Baffin Bay, Hudson Bay and the Canadian Arctic Archipelago, derived from ...

Microplastics in the Mediterranean: Variability From Observations and Model Analysis

Frontiers in Marine Science, 2022
In this study, the abundance and properties (size, shape, and polymer type) of microplastics (MPs) in sea surface water samples, collected during two sampling campaigns over 2018–2019, in four coastal areas of the Mediterranean Sea (Saronikos Gulf ...

Sensitivity of a Coarse‐Resolution Global Ocean Model to a Spatially Variable Neutral Diffusivity

Journal of Advances in Modeling Earth Systems, 2022
Motivated by recent advances in mapping mesoscale eddy tracer mixing in the ocean we evaluate the sensitivity of a coarse‐resolution global ocean model to a spatially variable neutral diffusion coefficient κn(x, y, z).

Climate change and ocean acidification impacts on lower trophic levels and the export of organic carbon to the deep ocean [PDF]

, 2013
Most future projections forecast significant and ongoing climate change during the 21st century, but with the severity of impacts dependent on efforts to restrain or reorganise human activity to limit carbon dioxide (CO2) emissions.

Basin-scale tracer replacement timescales in a one-degree global OGCM

Frontiers in Marine Science, 2023
This study investigates basin-scale tracer replacement timescales of the two polar oceans and the Atlantic, Indian, and Pacific Oceans using a one-degree global ocean-sea ice model that represents oceans under the largest Antarctic ice shelves, the ...
