Elevated cadmium accumulation in marine organisms from Terra Nova Bay (Antarctica) during 1989-1991
Entry ID:
Cadmium_marine_organisms_BTN
Summary
Abstract:
As a contribution towards identification of the principal environmental factors
involved in cadmium accumulation in Antarctic marine organisms and the establishment of a baseline near the Italian Antarctic Station Baia Terra Nova, surface sediments, plankton and benthic organisms were studied in coastal waters of Terra Nova Bay (Ross Sea). The cadmium content of sediments was similar to that ...  Geographic Coverage

The sampling area in Terra Nova Bay was on the inner continental shelf with
water depth ranging from 5 to 200 m. Samples of phytoplankton and zooplankton were collected with conical nylon nets towed just below the surface for 30 min. Surface sediments (to the top 3.0 cm) were collected on soft bottoms with a stainless steel box corer. Benthic organisms were sampled with a Van Veen grab or by dredging on hard bottoms. Fish specimens were obtained with a trammel-net or baited long-lines. Sample were frozen for storage and transport to Italy. In the laboratory, homogenized sediments and biological sub sample were digested and analyzed for Cd using a Perkin Elmer 4100 ZL.
