Physical and chemical properties of seawater for the North Sea, in each month of 1976

Series of 12 cruises carried out by Cefas in 1976 on board RV Corella and RV
Clione, resampling a grid of fixed stations every month throughout 1976. Data
provided: date; station number; time; position (latitude and longitude);
depth; tide direction; wind speed and direction. Environmental variables
measured include: temperature (surface and bottom), saliny, transparency (%),
nutrient concentrations (nitrite, nitrate, phosphate, silicate); chlorophyll-a
(total and nano); phaeophytin (total and nano). These data have been converted
into digital format (excel files); however there is more data collected during
the same survey (e.g. fish stomach content; fish larvae counts; phytoplankton
counts) that has not been converted and is still in paper format (paper
records are kept by Steve Milligan, Plankton Lab).

1976年，Cefas机构于RV Corella号和RV Clione号上实施了12次巡航活动，每月对固定站点网格进行重采样。所提供数据包括：日期；站点编号；时间；位置（纬度和经度）；水深；潮向；风速和风向。测量的环境变量包括：温度（表层和底层）、盐度、透明度（百分比）、营养物质浓度（亚硝酸盐、硝酸盐、磷酸盐、硅酸盐）；叶绿素a（总量和纳米级）；叶黄素（总量和纳米级）。这些数据已转换为数字格式（Excel文件）；然而，在相同调查期间收集的更多数据（例如，鱼类胃内容物；鱼苗计数；浮游植物计数）尚未转换，仍以纸质格式保存（纸质记录由Steve Milligan，浮游生物实验室保管）。
