Data_Sheet_1_Satellite Observations Are Needed to Understand Ocean Acidification and Multi-Stressor Impacts on Fish Stocks in a Changing Arctic Ocean.PDF

It is widely projected that under future climate scenarios the economic importance of Arctic Ocean fish stocks will increase. The Arctic Ocean is especially vulnerable to ocean acidification and already experiences low pH levels not projected to occur on a global scale until 2100. This paper outlines how ocean acidification must be considered with other potential stressors to accurately predict movement of fish stocks toward, and within, the Arctic and to inform future fish stock management strategies. First, we review the literature on ocean acidification impacts on fish, next we identify the main obstacles that currently preclude ocean acidification from Arctic fish stock projections. Finally, we provide a roadmap to describe how satellite observations can be used to address these gaps: improve knowledge, inform experimental studies, provide regional assessments of vulnerabilities, and implement appropriate management strategies. This roadmap sets out three inter-linked research priorities: (1) Establish organisms and ecosystem physiochemical baselines by increasing the coverage of Arctic physicochemical observations in both space and time; (2) Understand the variability of all stressors in space and time; (3) Map life histories and fish stocks against satellite-derived observations of stressors.

广泛预测，在未来的气候情景下，北极海洋鱼类资源的经济重要性将不断提升。北极海洋特别容易受到海洋酸化的影响，并且已经经历了预计在2100年全球范围内才可能出现的低pH值。本文阐述了海洋酸化必须与其他潜在的压力因素综合考虑，以准确预测鱼类资源在北极及其内部的移动，并为未来的鱼类资源管理策略提供信息。首先，我们回顾了海洋酸化对鱼类影响的相关文献；其次，我们确定了目前阻碍海洋酸化在北极鱼类资源预测中的主要障碍；最后，我们提出了一份路线图，描述如何利用卫星观测数据填补这些空白：提高知识水平、指导实验研究、提供区域脆弱性评估以及实施适当的管理策略。该路线图确定了三个相互关联的研究优先事项：（1）通过增加北极物理化学观测在空间和时间上的覆盖范围，建立生物和生态系统的物理化学基础；（2）理解所有压力因素在空间和时间上的变异性；（3）将生命历程和鱼类资源与卫星观测到的压力因素进行映射。
