Seawater temperature records for the UK Shelf - 11 - Cefas Lowestoft Sample Data Management System dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFAS73a6f865-60c6-470f-a2df-b2ff623600fc This dataset has been extracted as part of an exercise to assemble "all" Cefas Temperature Data and publish it in a Data paper. It is one of 17 Cefas data sources assembled. The Lowestoft Sample Data Management System (LSDM) was the tool used for tracking the ingestion, processing and analysis of marine water, sediment and radiological samples. It was replaced by the Cefas Laboratory Information Management System (LIMS) in 2015. This dataset is an extract from the LSDM for seawater temperature data (other data are in LIMS and the Cefas Data Hub). The Laboratory Sample Data Management system (LSDM) was the primary system used by Cefas (Lowestoft) before and throughout the 1990s (initially known as the Liquid Sample Data Management system). Its function was to provide a vehicle for the management of the ingestion, analysis and recording of measurements on marine samples, ranging from oceanographic water samples through sediments to “environmental materials” and radiological samples (see Sutton (1993) for an example of the supporting role of LSDM in relation to the, usually high level, scientific measurement systems of the day, Sauer et al (2002) for an example of its pivotal role in quality assured processes and analyses. As the work profile for the Ministry of Agriculture, Fisheries and Food Directorate of Fisheries Research changed, followed by the creation of Cefas and then Defra, the need for the centralised system for the management of an extensive suite of physical samples decreased. LSDM was closed down in 2015 with chemical data transferred to other systems. The temperature data held included the historical ferry routes and historical CTN data. The remainder, from a variety of programmes and cruises, are presented in this section. 20160627 20150203
