Western Antarctic Peninsula physical oceanography and spatio–temporal variability
Peninsula (WAP). The dataset offers the most long-lived consistent CTD-gridded observations of Antarctic waters collected anywhere in the Southern Ocean. The physical characteristics, water column structure and spatio–temporal variability of the various properties are examined for physically consistent and ecologically important patterns and modes of variability. Unique findings of note include...
متن کاملMarine pelagic ecosystems: the west Antarctic Peninsula.
The marine ecosystem of the West Antarctic Peninsula (WAP) extends from the Bellingshausen Sea to the northern tip of the peninsula and from the mostly glaciated coast across the continental shelf to the shelf break in the west. The glacially sculpted coastline along the peninsula is highly convoluted and characterized by deep embayments that are often interconnected by channels that facilitate...
متن کاملVariability in Sea-Ice Coverage and Ice-motion Dynamics in the PAL LTER Study Region West of the Antarctic Peninsula
Sea-ice conditions and kinematics are studied in the Palmer Long-Term Ecological Research (PAL LTER) study region west of the Antarctic Peninsula. Remote sensing data from ERS-1 Synthetic Aperture Radar (SAR) and Scatterometer (EScat) and from DMSP SSM/I, are used to study the influence of synoptic weather systems on sea-ice characteristics during July-August 1992. Weather records from Palmer S...
متن کاملTemporal and Regional Variability in the Skin Microbiome of Humpback Whales along the Western Antarctic Peninsula
The skin is the first line of defense between an animal and its environment, and disruptions in skin-associated microorganisms can be linked to an animal's health and nutritional state. To better understand the skin microbiome of large whales, high-throughput sequencing of partial small subunit rRNA genes was used to study the skin-associated bacteria of 89 seemingly healthy humpback whales (Me...
متن کاملSeasonal and interannual variability of phytoplankton biomass west of the Antarctic Peninsula
Ž . The spatial and temporal variability of phytoplankton biomass, estimated as chlorophyll-a chl-a concentration, is examined in the continental shelf-slope region west of the Antarctic Peninsula. Relationships between temporal observations Ž X X . in the nearshore Palmer Station grid 64846.77 S, 64804.36 W and spatial observations in a larger regional grid 200 km onroff-shore and 900 km along...
