The development of satellite derived nitrate and stratification indices for the southern Benguela ecosystem [PDF]

, 2013
An earth observation based study was conducted in the southern Benguela upwelling system, aimed at developing remotely sensed proxies to determine ecological conditions conducive to the formation of harmful algal blooms (HAB) which are endemic to the ...

Galicia upwelling revisited: out-of-season events in the rias (1967–2009)

Ciencias Marinas, 2011
Over the last decades several studies have been conducted on upwelling along the Galician coast that have significantly improved the knowledge of this process.

Sea surface temperatures of the western Arabian Sea during the last deglaciation. [PDF]

, 2007
In this study we present a sea surface temperature (SST) record from the western Arabian Sea for the last 20,000 years. We produced centennial-scale d18O and Mg/Ca SST time series of core NIOP929 with focus on the glacial-interglacial transition.

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

Journal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Coastal upwelling seen in ocean temperature data

, 2016
The phenomenon of wind-driven upwelling occurs when high coastal winds blow over the ocean surface, pushing warm surface waters offshore and allowing cooler, more nutrient rich water from below to rise up to the surface.

Observations of vortex dipoles on the Benguela upwelling front

, 1987
Vortex dipoles are unusual phenomena in the mesoscale turbulence of the world ocean which have, for the greater part, gone unnoticed until the advent of satellite remote sensing.

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Shelfbreak upwelling induced by alongshore currents: Analytical and numerical results [PDF]

, 2011
Alongshore flow in the direction of propagation of coastal trapped waves can result in upwelling at the shelfbreak. The intensity of this upwelling can be comparable in magnitude to wind-driven coastal upwelling, with its associated ecological features ...

First insights into oceanic manta ray movements in Japan using satellite telemetry

Journal of Fish Biology, EarlyView.
Abstract Japanese waters represent the northern distributional limit of the western Pacific distribution of the oceanic manta ray (Mobula birostris), yet movement ecology in this region remains poorly understood. We report movements of the first satellite‐tagged individual in Japan.

Upwelling and eddy activity in the Southern Queensland Coastal Marine Zone, Australia [PDF]

, 2016
Coastal upwelling systems are characterised by high primary productivity caused by the supply of nutrients into the surface layer of the ocean. These areas are key locations in global fish production despite their smaller size when compared with larger ...
