项目摘要

Predicting the impact and effects of changes on life in the oceans is of growing concern to marine scientists. Warming of the oceans and associated changes in the chemistry of sea water are expected to cause major shifts in abundance, diversity, and distribution of marine organisms, with possible consequences for natural capital and the capacity of the ocean to absorb carbon dioxide and other waste materials produced by humans. Presently it is unclear how future changes in PP may affect deep-sea community structure. Predicting the response of deep-sea communities to climate-driven shifts in PP is imperative given the importance of this environment to global bioabundance, biodiversity and ecosystem function. This project will use samples collected from the mid-1970s through to 2016 (no samples collected post 2016) to examine what changes have occurred in the benthic faunal community at species and functional diversity levels. Overarching aim: to quantify the extent of change in a deep-sea benthic community over a period spanning four decades - the longest benthic bathyal time series available globally, and to determine whether observed changes are linked with shifts in biotic (e.g., PP) and abiotic (e.g., temperature) variables. The work proposed here is the first of its kind at these depths and is important given known changes in productivity and water temperature and the impact these may have on the benthic ecosystem.

预测海洋生命的变化对海洋科学家的关注日益加剧。海洋的变暖以及海水化学的相关变化预计会导致海洋生物的丰度，多样性和分布的重大变化，并可能对自然资本以及海洋吸收二氧化碳和其他人类产生的其他废料的能力产生影响。目前尚不清楚PP的未来变化如何影响深海社区结构。鉴于这种环境对全球生物保存，生物多样性和生态系统功能的重要性，预测深海社区对PP气候驱动的转变的反应至关重要。该项目将使用从1970年代中期到2016年收集的样品（2016年之后未收集的样本）来检查物种和功能多样性水平的底栖动物群落中发生了什么变化。总体目的：在跨越四十年的一段时间内量化深海底栖群落的变化程度 - 最长的底栖bathyal Time序列在全球可用，并确定观察到的变化是否与生物（例如PP）和非生物（例如PP）和非生物（例如温度）变化有关。这里提出的工作是在这些深度上的第一项，鉴于生产率和水温的已知变化以及这些可能对底栖生态系统产生的影响很重要。
