项目摘要

The Land Ocean Carbon Transfer (LOCATE) programme has established genuinely new and highly effective collaborations across NOC, CEH, PML and BGS to deliver new understanding of terrigenous dissolved organic matter (tDOM) fluxes across streams, rivers, estuaries and into coastal seas and the global ocean. These fluxes collectively represent a significant and changing, yet poorly understood, component of the global C cycle. Together, we have already achieved the following, major advances: 1) the first internally consistent integration of tDOM fluxes to the tidal extent of GB rivers, demonstrating that coniferous forestry in uplands enhances this flux; 2) the largest study of tDOM transport across temperate estuarine waters, highlighting that the composition and fate of this material is strongly influenced by human activities on land; 3) the most comprehensive assessment of the distribution of tDOM throughout the North Sea, identifying that the bulk of tDOM exported from the Northwest European and Scandinavian landmasses must be buried or remineralized internally, with potential losses to the atmosphere; 4) the development of a fundamentally new model, UniDOM, that unifies concepts, state variables and parameterisations of tDOM turnover across the land-ocean aquatic continuum (LOAC). Our developments in understanding the fluxes and fate of tDOM have brought into sharp focus how little is known about greenhouse gas (GHGs; CO2, CH4, N2O) fluxes and the processes that control these in aquatic ecosystems. Our key stakeholders, including BEIS and major water companies, recognise that this lack of understanding hinders national GHG emissions reporting and the development of sustainable land- and water management policies to enable the UK government to achieve net-zero GHG emissions by 2050. Building upon our previous achievements, our proposed extension activities aim to:1) develop a GHG budget for the GB LOAC, 2) understand the biotic and abiotic processes that control these, and 3) assess the influence of human activities. We will achieve these through a series of interconnected objectives that combine desk-based syntheses and modelling activities, analysis of archived samples from our original year-long GB-scale field programme, use of our legacy focal catchments to establish a suite of baseline observations, and stakeholder engagement. We will continue to work with our diverse range of regional, national and international stakeholders to identify where and how this new understanding can achieve beneficial outcomes for policies and practices relating to C sequestration and climate regulation.

土地海洋碳转移（定位）计划已经在NOC，CEH，PML和BGS建立了真正的新型和高效的合作，以对跨溪流，河流，河口以及沿海海洋以及沿海海洋以及沿海和沿海海洋以及沿海和沿海海洋以及沿海和沿海海洋以及沿海和沿海海洋以及沿海地区以及沿海地区以及全球海洋。这些通量统称代表了全球C周期的一个重大而变化但知之甚少的组成部分。总之，我们已经实现了以下主要进步：1）TDOR通量在GB河流的潮汐范围内首次内部一致的整合，表明高地的针叶林林业增强了这种通量； 2）跨温带河口水域的TDON运输的最大研究，强调了这种材料的组成和命运受到人类在陆地活动的强烈影响； 3）对整个北海的TDOR分布的最全面评估，确定必须在内部埋葬或回忆起从欧洲西北和斯堪的纳维亚的陆地出口的大部分TDOM，并可能损失大气； 4）从根本上新的模型Unidom的开发，该模型统一了整个土地海水连续体（LOAC）的概念，状态变量和参数。我们在理解TDOM的通量和命运方面的发展已引起人们的重点，对温室气体（GHG； CO2； CO2，CH4，N2O）通量知之甚少，以及在水生生态系统中控制这些的过程。我们的主要利益相关者，包括贝斯和主要水公司，都认识到，这种缺乏理解阻碍了国家温室气体排放的报告，并制定可持续的土地和水管理政策，使英国政府能够到2050年实现净零温室气体的排放。我们以前的成就，我们提出的扩展活动的目的是：1）为GB LOAC制定GHG预算，2）了解控制这些的生物和非生物过程，以及3）评估人类活动的影响。我们将通过一系列相互联系的目标来实现这些目标，这些目标将基于桌面的合成和建模活动结合在一起，对我们原始一年的GB规模现场计划中的存档样本进行分析，使用我们的旧式焦点集水集以建立一套基线观察，，，和利益相关者的参与。我们将继续与各种各样的区域，国家和国际利益相关者合作，以确定这种新的理解在哪里以及如何实现与C隔离和气候监管有关的政策和实践的有益结果。
