Polycyclic Aromatic Hydrocarbons in Kenyan Coral Reef Sediments: Distribution, Sources, and Equivalent Ecological Risks

This study evaluated the spatial distribution, source apportionment, and equivalent ecological risk of polycyclic aromatic hydrocarbons (PAHs) in 18 surface sediments across four Kenyan coral reef ecosystems (Malindi, Watamu, Kilifi, and Mombasa-Nyali). Total PAH concentrations (...

A global consistent database of plankton and detritus from in situ imaging by the Underwater Vision Profiler 5

Plankton and detritus are essential components of the Earth's oceans influencing biogeochemical cycles and carbon sequestration. Climate change impacts their composition and fluxes, and marine ecosystems as a whole. To improve our understanding of these changes, standardized obse...

Steric‐Setup Effects on US East Coast Sea‐Level Change

Abstract The extent to which coastal sea levels co‐vary with open‐ocean variability is explored through evaluation of a balanced dynamics framework relating sea level with pressure, density, and velocity along the continental shelf and slope seafloor. Using high‐resolution region...

Beyond wind-induced upwelling: diverse drivers of future productivity in eastern boundary upwelling systems

Abstract. Eastern Boundary Upwelling Systems (EBUS) contribute disproportionately to global marine productivity and fisheries, yet their response to climate change remains poorly understood. Given the essential ecosystem services they support, improving projections of future EBUS...

An energetic perspective on the impact of the Atlantic Multidecadal Variability on the West African Monsoon

Abstract. This study explores mechanisms by which the Atlantic Multidecadal Variability (AMV) drives multidecadal changes in the West African Monsoon (WAM), with a focus on Sahel rainfall. We investigate this connection through an energetic perspective using atmosphere-ocean coup...

Detectability of Forced ENSO Changes Under Global Warming: Insights From the Recharge Oscillator

Abstract We use perfect‐model, large‐ensemble nonlinear Recharge Oscillator (RO) simulations to quantify ENSO internal variability and the detectability of forced changes in ENSO characteristics. Fixed‐parameter simulations show that linear trends in ENSO standard deviation, peri...

Sensitivity of the Bootstrap sea ice concentration algorithm to surface parameters in the Antarctic marginal ice zone using passive microwave retrievals

Abstract. Changes in sea ice concentration (SIC) and derived sea ice extent have been monitored using microwave radiometers since the late 1970s, providing information about the polar response to climate change, making SIC an invaluable variable for numerical models. Antarctic se...

Will work for sardines: 20 years of animal-borne ocean observing by Australia’s Integrated Marine Observing System (IMOS) Animal Tagging Facility

The world’s ocean stores ~90% of the excess heat generated by anthropogenic global warming, making sustained ocean observations essential for understanding physical, biological and climate processes. Here, we describe how the Integrated Marine Observing System (IMOS) Animal Taggi...
