This dataset consists of measurements of underway meteorology, navigation and sea surface hydrography. The data were collected on RRS Discovery cruise DY051 through the Goban Spur and Rockall Trough areas of the Northeast Atlantic. The cruise spanned the 13th of May to the 3rd of June 2016. Navigation data were collected using an Applanix POSMV system and meteorology and sea surface hydrography were collected using the NMF Surfmet system. Both systems were run through the duration of the cruise, excepting times for cleaning, entering and leaving port, and while alongside. The data were collected as part of the 'MAC-EXP: Development of a pressurised sampling, experimentation and cultivation system for deep-sea sediments' project. The project aims to develop a flexible, cost-effective alternative to in situ experimentation: a pressure-coring, experimentation and cultivation system that enables studies of deep-sea prokaryote biodiversity and ecosystem functioning, under ambient or manipulated pressure, temperature and oxygen conditions from any medium-sized oceangoing research ship with coring capability. This Multiple-Autoclave-Coring and Experimentation system (MAC-EXP) will aim to provide the possibility to systematically test the influence of environmental parameters, such as pressure, oxygen availability or pH on deep-sea organisms and their biochemistry, as well as on rates and pathways of biogeochemical and geomicrobial processes. The system will also aim to allow pioneering work in the field of marine biodiscovery: secondary metabolites from marine microorganisms are a rich source of chemical diversity and several marine-microbe-derived compounds are now in clinical trials. Funding was provided by NERC Standard grants NE/I023465/1 (lead) and NE/I024232/1. The lead grant covered 01 February 2013 to 31 December 2016 and the child grant covered 01 April 2012 to 31 March 2015. Professor Ursula Witte of University of Aberdeen, Institute of Biological and Environmental Sciences was the principal investigator for the lead grant. Professor Ronald J Parkes of Cardiff University School of Earth and Ocean Sciences was the principal investigator for the child grant. The data have not yet been received by BODC.
