2012-2013 University of Plymouth Falmouth maerl bed infauna and sediment survey using diver cores

Survey to establish the infaunal species composition and sediment properties of maerl bed habitats in Falmouth Harbour, from SCUBA diver collected core samples. Surveys were conducted in response to proposed dredging activities to deepen the shipping channel. Core samples collected by divers September - November 2012 and July - August 2013 were used to assess habitat quality and species distribution by quantifying the abundance of infauna and analysing organic content, particle size and maerl structure. There were 6 sites divided into three 5m2 plots. SCUBA divers collected 8 maerl core samples per plot: 5 cores for faunal analysis and 3 cores for sediment and organic content analysis.

为探究法尔茅斯港中珊瑚藻床栖息地的底栖物种组成与沉积物特性，进行了相关调查研究。该研究旨在对拟议中的航道疏浚活动进行响应，以深化航运水道。通过潜水员采集的核心样本，对2012年9月至11月及2013年7月至8月期间收集的核心样本进行了利用，以量化底栖生物丰度和分析有机质含量、颗粒大小以及珊瑚藻结构，从而评估栖息地品质及物种分布。研究共划分了6个研究点，每个点分为三个5平方米的子区域。潜水员在每个子区域内采集了8个珊瑚藻核心样本：其中5个用于动物群落分析，3个用于沉积物和有机质分析。此外，请参考2011年普利茅斯大学法尔茅斯拖曳式水下视频珊瑚藻及其附着生物调查报告，以及2012年普利茅斯大学法尔茅斯拖曳式水下视频珊瑚藻及其附着生物调查报告，以获取拖曳视频横切数据。
