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.

为确立法尔茅斯港海藻床栖息地的底栖物种组成及沉积物特性，进行了针对潜水员采集的柱状样调查。此次调查旨在响应拓宽航道所提出的疏浚活动。2012年9月至11月及2013年7月至8月期间，潜水员采集的柱状样被用于评估栖息地质量与物种分布，通过量化底栖生物的丰度和分析有机质含量、颗粒尺寸及海藻床结构来实现。调查分为6个地点，每个地点划分为3个5平方米的样方。在每个样方中，潜水员采集了8个海藻床柱状样：其中5个用于动物群分析，3个用于沉积物和有机质含量分析。请参阅2011年普利茅斯大学法尔茅斯拖曳式水下视频海藻床及相关表生生物调查，以及2012年普利茅斯大学法尔茅斯拖曳式水下视频海藻床及相关表生生物调查，以获取拖曳视频横断面数据。
