River Research and Applications, EarlyView.ABSTRACT Building an understanding of river ecosystems often involves integrating information from different locations, spatial scales and points in time. Geomorphologists and ecologists have long considered ways to explore river ecosystems at different, hierarchical, spatial scales so that features observed locally can be linked to the character of ...

On the structural changes in the Brewer-Dobson circulation after 2000 [PDF]
, 2010 In this paper we present evidence that the observed increase in tropical upwelling after the year 2000 may be attributed to a change in the Brewer-Dobson circulation pattern.

Remote Sensing in Ecology and Conservation, EarlyView.Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

Diversity, 2020 The input of new nutrients by upwelling in shelf waters, and the associated carbon and nitrogen fluxes, can be traced by their stable isotope signatures in organic matter.

Weather, EarlyView.The frequency of summer nights whose minimum temperature remains above a rarely exceeded threshold – such as the ‘Tropical Night’ 20°C requirement – provides one measure of climate warming. Unfortunately, relying on nocturnal temperature minima for this may select conditions when naturally ventilated thermometers, such as those housed within Stevenson ...

Communications Earth & Environment, 2023 In California offshore waters, sustained northwesterly winds have been identified as a key resource that can contribute substantially to renewable energy goals. However, the development of large-scale offshore wind farms can reduce the wind stress at the

Greenhouse gases in cold water filaments in the Arabian Sea during the Southwest Monsoon [PDF]
, 1999 The distribution of partial pressure of carbon dioxide and the concentrations of nitrous oxide and methane were investigated in a cold water filament near the coastal upwelling region off Oman at the beginning of the southwest monsoon in 1997.

Archaeometry, EarlyView.Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Biological and physical oceanographic observations pertaining to the trawl fishery in a region of persistent coastal upwelling [PDF]
An upwelling episode in the Point Sal region of the central California coast is examined by using data obtained by a data buoy. The episodes was interrupted by the abrupt abatement of the strong wind which promotes coastal upwelling.
