Persistent organic pollutants in benthic and pelagic organisms off Adélie Land, Antarctica.
The concentrations of polychlorinated biphenyls (PCB), hexachlorobenzene (HCB), pentachlorobenzene (PeCB) and polybrominated diphenylethers (PBDE) were described in benthic and pelagic species collected off Adélie Land, Antarctica. Strong differences were observed among species, with reduced PeCB and HCB levels in benthic species, and elevated PCB levels in the Antarctic yellowbelly rockcod, th...
متن کاملSatellite remote sensing of surface oceanic fronts in coastal waters off west–central Florida
Article history: Received 4 October 2007 Received in revised form 4 February 2008 Accepted 9 February 2008 Two algorithms designed to detect deepwater oceanic features and arbitrary edge profiles were tuned to automatically delineate fronts in coastal waters off west–central Florida using satellite-derived sea surface temperature (SST), chlorophyll-a concentration (Chl), normalized water-leavin...
متن کاملHabitat use and sex-specific foraging behaviour of Adélie penguins throughout the breeding season in Adélie Land, East Antarctica
BACKGROUND Marine predators are ecosystem sentinels because their foraging behaviour and reproductive success reflect the variability occurring in the lower trophic levels of the ecosystem. In an era of environmental change, monitoring top predators species can provide valuable insights into the zones of ecological importance that need to be protected. In this context, we monitored the Adélie p...
متن کاملBlood analytes of oceanic-juvenile loggerhead sea turtles (Caretta caretta) from Azorean waters: reference intervals, size-relevant correlations and comparisons to neritic loggerheads from western Atlantic coastal waters
Blood analyte reference intervals are scarce for immature life stages of the loggerhead sea turtle (Caretta caretta). The objectives of this study were to (1) document reference intervals of packed cell volume (PCV) and 20 plasma chemistry analytes from wild oceanic-juvenile stage loggerhead turtles from Azorean waters, (2) investigate correlations with body size (minimum straight carapace leng...
متن کاملRetrieval of particulate backscattering in coastal/oceanic waters
Accurate retrieval of particulate backscattering coefficients has been a great challenge in optically complex Case 2 waters. Although several models exist for retrieval of the Inherent Optical Properties (IOP’s) such as particulate backscattering (bbp) from the remote sensing reflectance, these models produce bbp with high errors mainly because of improper parameterization or inappropriate defi...
