EXCHANGE Campaign 1: A Community-Driven Baseline Characterization of Soils, Sediments, and Water Across Coastal Gradients

The EXploration of Coastal Hydrobiogeochemistry Across a Network of Gradients and Experiments (EXCHANGE) program is a consortium of scientists working together to improve our understanding of how the two-way exchange of water between estuaries or large lake lacustuaries and the terrestrial landscape influence the state and function of ecosystems across the coastal interface. EXCHANGE Campaign 1 (EC1) focuses on the spatial variation in biogeochemical structure and function at the coastal terrestrial-aquatic interface (TAI). In the Fall of 2021, the EXCHANGE Consortium gathered samples from 52 TAIs. Samples collected from EC1 were analyzed for bulk geochemical parameters, bulk physicochemical parameters, organic matter characteristics, and redox-sensitive elements. Please download ec1_README.pdf for a complete list of available data in each .zip folder, package version history, and detailed information about the project. This README will serve as the central place for EC1 Data Package updates.

跨梯度与实验网络的海岸水生物地球化学探索（EXCHANGE）计划是一个由科研人员组成的联盟，旨在深化对河口或大型湖沼与陆地景观之间双向水体交换如何影响海岸界面生态系统状态与功能的认知。EXCHANGE第1期科考活动（EC1）聚焦于海岸陆水界面（terrestrial-aquatic interface, TAI）的生物地球化学结构与功能的空间分异特征。2021年秋季，EXCHANGE科研联盟采集了52个陆水界面的样品。EC1采集的样品针对全量地球化学参数、全量物理化学参数、有机质特征以及氧化还原敏感元素开展了分析测试。请下载ec1_README.pdf以获取各压缩包内可用数据的完整清单、数据包版本更新历史以及本项目的详细说明信息。本README文档将作为EC1数据包后续更新的官方发布渠道。
