Carbon Retention in a Colored Ocean (CARIACO)

9216626穆勒-卡格 这是一项关于近地表地球化学过程与微粒物质沿着大陆边向下通量的关系的研究，在大陆边，向下斜坡横向损失到海洋内部的程度是最小的。具体而言，位于加勒比海南部大陆边缘的一个低压区Cariaco盆地的低成本海洋边缘时间序列站将受到影响。 将使用自动化的摩尔捕集器在4个深度进行每月水文预测和每两周一次的沉积物通量，将使用位于贝内苏埃拉加拉加斯的天线收集高分辨率卫星数据。该计划被称为CARIACO（Carbon Retention In A Colored Ocean）。 CARIACO计划的目标是：a）量化影响营养物垂直通量、碳吸收和碳沉积的海洋学过程，包括风速、海平面（作为地转流强度的指标）、河流流量、海面温度和缺氧盆地上方的辐照度;确定受季节性上升流和河流排放影响的地区的生态化学通量的变化; c）量化初级生产相对于颗粒和溶解物质的陆源输入在向下通量和沉积物储存中的相对重要性;（d）确定水体中浮游生物的季节分类组成，重点是浮游植物和有孔虫物种的垂直变化;（e）建立一个二维数值模型，以便检查种群反应的年度周期、垂直生物通量和深层碎屑的降解;（f）研究水柱海洋学过程与沉积物通量之间的关系，以了解沉积物纹的起源及其与过去气候变化的关系。

9216626 MULLER-KARGER This is a study of the relation of near surface biogeochemical processes to the downward flux of particulate materials along a continental margin where down-slope lateral losses into the ocean's interior are minimal. Specifically, low-cost ocean margin time series station in the Cariaco Basin, a depression located on the continental margin of the southern Caribbean Sea, will be inflemeated. Monthly hydrographic casts and bi-weekly sediment flux at 4 depths using automated moore traps will the conducted high resolution satellite data will be collected using an antenna located in Caracas, Benezuela. This program is identified is as CARIACO (CArbon Retention In A Colored Ocean). The goals of the CARIACO program are to: a) quantify oceanographic processes that affect the vertical flux of nutrients, carbon uptake, and carbon deposition, including the interaction between wind speed, sea level (as an indicator of geostrophic current strength), river discharge, sea surface temperature, and irradiance above an anoxic basin; to define variability in biogeochemcial fluxes in an area affected by seasonal upwelling and river discharge; c) quantify the relative importance of primary production versus terrigenous inputs of particulate and dissolved materials in the downward flux and sediments storage; d) determine the seasonal taxonomic composition of plankton in the water column, with emphasis on vertical variations of phytoplankton and foraminifera species; e) develop a two-dimensional numerical model the allows examination of the annual cycle of population responses, vertical biogenic fluxes, and degradation of detritus at depth; and f) examine the relationship between water-column oceanographic processes and sediment fluxes in order to understand the origin of sediment varves and their relationship to past climate change.
