Mooring B: North Central Ross Sea, Joides Basin - Antarctica

The Mooring B is located in the North-central Ross Sea in the Joides Basin. The mooring is equiped with sediment traps, currentometers, trasmissometer, fluorimeter and CTD. The study of mooring can be consider part of the activities conduct in the framework of the research project "ABIOCLEAR - Antarctic biogeochemical cycles - climatic and paleoclimatic reconstructions. (Resp. M. Ravaioli)". Such Project is the natural prosecution of previous research activity carried out from 1987. Objectives : Study of the particle fluxes towards the marine bottom sediment, in particular with the aim to obtain quali/quantitative estimate of the biogenica component coming from the primary production. Analysis of the vertical rain rate processes and, therefore, the marine cycle of the main biogenic particles such as Carbon and Silica. Try to obtain mass budgets of these parameters, estimating their cycle in the water column until the burial processes in sediments. From apparent accumulate rate calculated in the bottom sediment we will tried to discriminate the real vertical fluxes (Rain Rate) from the horizontal input from sediment remobilization processes. Acquisition and elaboration of long time series of data. Collection of bottom Sediment samples to estimate the variations of the productivity and the paleoproductivity in the area. Historical time series of Mooring B: Primary productivity data (every three years), fitoplancton, New and regenerated productivity, Seasonal, annual and interannual fluxes measure, monthly Particles samples, current velocity, water salinity, temperature and torbidity, Water-sediment interface measure. Biogeochemical parameters. Radiometrical Data, Mineralogical and grain size characterization. Nutrient, metals. Biostratigraphy interpretations. Lidar data are also available from 1997.
