Estimates of nitrogen and phosphorus excretion rates in individual marine and estuarine animals

This dataset contains nitrogen and phosphorus excretion rate, as
well as dry biomass, estimates for individual vertebrate and
invertebrate animals in marine and estuarine environments. This
dataset is a product of an LTER Synthesis Working Group aimed at
evaluating the spatiotemporal variability in consumer nutrient
dynamics in the wake of global change across eight long-term
ecological research projects. These projects include seven
long-term ecological research programs (LTER) funded by the
National Science Foundation: (1) California Current Ecosystem, (2)
Florida Coastal Everglades, (3) Moorea Coral Reef, (4) Northern
Gulf of Alaska, (5) Plum Island Ecosystems, (6) Santa Barbara
Coastal, and (7) Virginia Coast Reserve LTER projects.
Additionally, the dataset includes data from (8) The Partnership
for Interdisciplinary Science of Coastal Oceans (PISCO) research
program. The temporal coverage of each time series data varies
among projects, with the earliest record in 1997 and the most
recent in 2023.

This data package also includes five R scripts used for data
harmonization, identical to those in the Initial Release of the
LTER Synthesis Working Group: Consumer-Mediated Nutrient Dynamics
Project, v1.1.0. You can find the release in GitHub here:

本数据集收录了海洋与河口环境中各类脊椎动物与无脊椎动物个体的氮磷排泄率、干生物量及其相关估算值。本数据集由长期生态研究（Long Term Ecological Research, LTER）综合工作组研制，旨在评估全球变化背景下消费者营养动态的时空变异特征，该项工作依托八项长期生态研究项目开展。其中七项为美国国家科学基金会资助的长期生态研究计划，具体包括：(1) 加利福尼亚海流生态系统、(2) 佛罗里达沿海大沼泽地、(3) 莫雷阿珊瑚礁、(4) 阿拉斯加北湾、(5) 普拉姆岛生态系统、(6) 圣巴巴拉沿海、(7) 弗吉尼亚海岸保护区长期生态研究项目；此外，数据集还纳入了(8) 海岸海洋跨学科科学合作组织（Partnership for Interdisciplinary Science of Coastal Oceans, PISCO）研究计划的相关数据。各项目的时间序列数据覆盖时长存在差异，最早记录始于1997年，最新记录截至2023年。

本数据包还附带五份用于数据协调的R脚本，其内容与LTER综合工作组“消费者介导营养动态项目”v1.1.0初始版本中的脚本完全一致。您可通过以下GitHub链接获取该版本的发布内容：https://github.com/lter/lterwg-marine-cnd/releases/tag/v1.1.0。
