2014 JNCC/MSS Solan Bank Reef Drop Down Video Survey

The Joint Nature Conservation Committee (JNCC) and Marine Scotland Science (MSS) undertook an offshore seabed survey of Solan Bank Reef Site of Community Importance (SCI) on the MRV Scotia from 28 October 2014 to 9 November 2014 (Cruise Code: 1714S).
The survey was planned with the aim of evaluating whether sponge morphological abundance can be sufficiently measured from drop down camera images and videos, to inform development of a national indicator of 'Good Environmental Status' as part of the UK's obligations under the Marine Strategy Framework Directive (MSFD). Initial baseline data on epifaunal communities and associated environmental variables in the Solan Bank SCI was collected, to assist in determining whether the indicator is viable for UK offshore waters.
Data collected on this survey was assessed to determine whether there are sufficient abundances of different sponge morphologies at the site to detect significant change in these communities. 166 combined Drop Frame Drop Down Video (DDV) and Seabird 19 (CTD) transects were completed and Acoustic Doppler Current Profile (ADCP) data from 3 stations were collected.

联合自然保护委员会（JNCC）与苏格兰海洋科学（MSS）在2014年10月28日至11月9日，于MRV Scotia号上对社区重要性海域（SCI）的Solan Bank礁进行了一次海上海底调查。此次调查旨在评估海绵形态丰度是否能够通过水下摄像头图像和视频资料得到充分测量，从而为英国履行海洋战略框架指令（MSFD）下的义务，开发国家层面的‘良好环境状态’指标提供信息。在Solan Bank SCI海域，收集了关于附生生物群落及其相关环境变量的初步基线数据，以协助判断该指标是否适用于英国近海。调查收集的数据经过评估，以确定该海域是否拥有足够不同海绵形态的丰度，以便检测这些群落中的显著变化。共完成了166条结合了降帧水下摄像头视频（DDV）和Seabird 19（CTD）的横切线，并从3个站点收集了声学多普勒流速剖面（ADCP）数据。
