Hace 5 días · Projected upwelling season (March–August) changes in (a) total vertical transport (Coastal Upwelling Transport Index), (b) nitrate concentration at the base of the mixed layer, (c) nitrate flux into the mixed layer (Biologically Effective Upwelling Transport Index), and (d) phytoplankton biomass in the upper 50 m between historical (1991–2020) and future (2071–2100) epochs.
Hace 2 días · Ocean fronts, characterized by narrow zones with sharp changes in water properties, are vital hotspots for ecosystem services and key regulators of regional and global climates. Global change is ...
Hace 5 días · Historical (1991–2020) upwelling season (March–August) (a) mixed layer depth (MLD) and (e) nitrate concentration at 50 m depth from the ensemble average of downscaled simulations.
Hace 1 día · When dealing with currents, understanding the concept of upwelling is essential. Upwelling occurs when deep, cold water rises to the surface, bringing with it nutrients that support a thriving ecosystem. Spearfishers can take advantage of upwelling areas to find an abundance of fish congregating to feed on the nutrient-rich waters.
Hace 4 días · Mantle plumes are thought to be zones of upwelling hot mantle rock, the surface expressions of which often include large igneous provinces, oceanic islands, seamounts, continental flood basalts, and linear volcanic chains in the oceans and on the continents called "hotspot tracks".
Hace 3 días · The drivers and source of these centennial-scale CO 2 jumps are unknown. The proposed mechanisms include enhanced ocean–atmosphere CO 2 exchange in the Southern Ocean (via wind-driven upwelling of carbon-rich deep waters or invigorated convection), surface ocean temperature changes (impacting CO 2 solubility), biomass burning (via NH subtropical wildfires), or a combination of mechanisms (18 ...
Hace 3 días · Accurate and continuous estimation of surface albedo is vital for assessing and understanding land–surface–atmosphere interactions. We developed a method for estimating instantaneous all-sky at-surface shortwave upwelling radiance and albedo over the Tibetan Plateau. The method accounts for the complex interplay of topography and atmospheric interactions and aims to mitigate the occurrence ...
