Sub-Antarctic islands represent critical breeding habitats for land-based top predators that dominate Southern Ocean food webs. Reproduction and molting incur high energetic demands that are sustained at the sub-Antarctic Prince Edward Islands (PEIs) by both inshore (phytoplankton blooms; "island mass effect"; autochthonous) and offshore (allochthonous) productivity. As the relative contributio...

The waters around the Pribilof Islands in the southeast Bering Sea are a center of abundance for age-0 walleye pollock (Theragra chalcogramma). Each spring and summer a tidal front is formed around the islands separating a well-mixed inshore habitat from a stratified offshore habitat. The objective of this study was to assess the foraging impact on zooplankton by age-0 pollock in the vicinity o...

Huge imbalance of different scenes’ sample numbers seriously reduces synthetic aperture radar (SAR) ship detection accuracy. Thus, to solve this problem, letter proposes a balance scene learning mechanism (BSLM) for offshore and inshore in SAR images. BSLM involves three steps: 1) based on unsupervised representation learning, generative adversarial network (GAN) is used extract the features im...

A high-resolution coastal Finite-Volume Community Ocean Model (FVCOM) has been configured to simulate the water circulation in Eastern Shore Islands (ESI) archipelago on Scotian Shelf. Circulation this area is characterized by complex interactions between irregular coastline, a dense archipelago, tides, wind, and subtidal currents. outputs show close agreement with current, hydrographic observa...

Scleractinian coral are experiencing unprecedented rates of mortality due to increases in sea surface temperatures in response to global climate change. Some coral species however, survive high temperature events due to a reduced susceptibility to bleaching. We investigated the relationship between bleaching susceptibility and expression of five metabolically related genes of Symbiodinium spp. ...

After the catastrophic losses of three Hull deep sea trawlers in 1968, the Committee of Inquiry into Trawler Safety (CITS) was established. Fourteen months later, CITS reported on factors affecting the safety of deep sea trawlers and their crews. Pre-CITS (1961-70) and post-CITS (1971-80) crude mortality rates for accidents at work are compared for "deep sea" fishermen (those working on vessels...

Heaviside’s dolphin (Cephalorhynchus heavisidii) is a coastal delphinid with a limited inshore distribution off the west coast of southern Africa. Knowledge of its habitat usage is an essential precursor to assessing its potential vulnerability to fisheries interactions. Six Heaviside’s dolphins (1 male and 5 females) were fitted with satellitelinked transmitters in 2004, and tracked for up to ...

BACKGROUND Declining water quality coupled with the effects of climate change are rapidly increasing coral diseases on reefs worldwide, although links between coral diseases and environmental parameters remain poorly understood. This is the first study to document a correlation between coral disease and water quality on an inshore reef. METHODOLOGY/PRINCIPAL FINDINGS The temporal dynamics of ...
