项目摘要

Our object is to understand how large, and how variable, are sources and sinks of greenhouse gases to the atmosphere from the North Atlantic. We aim to be able to describe how these have changed in the recent past and how they will change in the future under different climate scenarios. Most effort will be concentrated on carbon dioxide, and we will deliver a comprehensive budgeting of natural and anthropogenic components of the carbon cycle in the North Atlantic and understanding of why the air-sea fluxes of CO2 vary regionally, seasonally and multi-annually. Observations of CH4 and N2O and estimates of their regional fluxes will additionally be made. We, in collaboration with our partner institutions in Europe and the US, will undertake surface measurements of CO2 air-sea fluxes made from networks of voluntary observing ships and at fixed sites. These will be synthesised with observations from hydrographic sections of the interior carbon content. We will thus obtain accurate estimates of the uptake, present storage, and net transport of anthropogenic carbon, and variability in the natural uptake and release of atmospheric CO2 by the N. Atlantic. In parallel with direct estimates made from these observations, forward and inverse models (of both atmospheric and oceanic kinds) of these fluxes will be developed. The main hypotheses are (1) that past uptake and variability of CO2 in the region can be quantified by examination of the deep carbon inventory in the Atlantic, (2) that the present observed variability in CO2 uptake is due to a combination of biological and physical processes that are driven by climatic variations, the main factors being captured by ocean carbon simulations embedded in climate models, and (3) these variations (past, present and future) are due to a combination of variability internal to the climate system and external anthropogenic forcing - in proportions we will determine. Objectives are (1) a template for operational forecasting of the fluxes of GHGs into and out of the N. Atlantic, to be implemented as part of ICOS and in combination with ECMWF (2) an understanding of that sink that can be used to improve projections of how the ocean CO2 sink will change in the future, and (3) a quantitative understanding of how and why Atlantic Ocean uptake of anthropogenic CO2 has changed as a result of climate change over the last 100 years.

我们的目的是了解从北大西洋大西洋大气中的温室气体和水槽的大小和可变程度。我们的目的是能够描述最近的变化以及在不同的气候场景下如何在将来发生变化。大多数努力将集中在二氧化碳上，我们将对北大西洋的碳循环的天然和人为成分进行全面的预算，并了解为什么二氧化碳的空气通量在区域，季节性和跨多年度上变化。还将对CH4和N2O的观察以及其区域通量的估计值进行。我们将与我们在欧洲和美国的合作伙伴机构合作，将对由自愿观察船只和固定地点网络制成的CO2空气通量进行表面测量。这些将与内部碳含量的水文切片的观察结果合成。因此，我们将获得人为碳的摄取，当前存储和净运输的准确估计，以及N. Atlantic的自然摄取和大气CO2释放的可变性。与这些观测值的直接估计以及这些通量的正向和逆模型（大气和海洋种类）的直接估计。 The main hypotheses are (1) that past uptake and variability of CO2 in the region can be quantified by examination of the deep carbon inventory in the Atlantic, (2) that the present observed variability in CO2 uptake is due to a combination of biological and physical processes that are driven by climatic variations, the main factors being captured by ocean carbon simulations embedded in climate models, and (3) these variations (past, present and未来）是由于气候系统内部的变异性和外部人为强迫的组合 - 我们将确定的比例。 Objectives are (1) a template for operational forecasting of the fluxes of GHGs into and out of the N.
