PROPHEZE Project Data Set - physical and biological characteristics of shelf waters of the Celtic Sea, 2000

The data set contains a variety of physical, chemical and biological parameters. Hydrographic profiles provided temperature, salinity, fluorescence, dissolved oxygen and transmissance measurements, which were supplemented by time series of surface ocean and meteorological properties. Time series of current velocities, temperature and sea level were also collected. Biogeochemical and biological analyses of water samples provided nutrient, phytoplankton and zooplankton data, while production data were derived from incubation experiments. The data were collected at seven stations in the Celtic Sea with varying physical and biological characteristics. Fieldwork was undertaken between 15th and 29th May 2000, with each station being occupied for 24 hours. Data were collected via shipboard deployment of CTD profilers and undulators with accompanying auxiliary sensors, and discrete water sampling. Further data were obtained from three moorings including acoustic Doppler current profilers (ADCPs), temperature recorders and bottom pressure recorders that were also deployed and recovered during the study period. Measurements were collected during RRS Discovery cruise D246 as part of the multidisciplinary study of the interactions between physical processes and biological production in contrasting pelagic shelf waters. An additional goal of the study was to map the tidal front situated in the St George's Channel. The study was co-ordinated by Plymouth Marine Laboratory and the research involved 28 scientists and technicians from 14 separate institutions situated in five different countries. Data are managed by the British Oceanographic Data Centre.

本数据集囊括了丰富多样的物理、化学及生物参数。所提供的海洋水文剖面资料包括温度、盐度、荧光、溶解氧及透射率等测量数据，并辅以表层海洋及气象属性的时间序列数据。同时，还收集了流速、温度及海平面的时间序列数据。通过对水样进行生物地球化学及生物分析，获得了营养物质、浮游植物和浮游动物数据，而生产数据则来源于培育实验。数据采集于凯尔特海七个物理和生物特性各异的海站。实地考察于2000年5月15日至29日进行，每个海站停留24小时。数据通过船舶搭载的CTD剖面仪和摆动仪及其辅助传感器，以及离散的水样采集获得。此外，在研究期间，还从三个浮标中获得了进一步的数据，包括声学多普勒流速剖面仪（ADCP）、温度记录仪和底压记录仪，这些设备亦在此期间被布设和回收。测量数据收集于RRS Discovery巡航D246期间，作为对对比性浮游大陆架水域中物理过程与生物生产相互作用的多学科研究的一部分。研究的一个额外目标是绘制位于圣乔治海峡的潮汐锋。该研究由普利茅斯海洋实验室协调，涉及来自五个不同国家14个不同机构的28位科学家和技术人员。数据由英国海洋数据中心进行管理。
