dissolved oxygen (uM), phosphates (uM), silicates (uM).
*Instruments and methods: Nansen bottles with reversible thermometers,

sedimentary method (Morozova - Vodianitskaya 1948, Utermohl method variant);
microscope counting of algae species cells, from subsamples of the
0.5 -1.0 liter samples; biomass estimation trough multiplying numerical
density with species average weight.

*Format: Header data file format of the NATO TU-BS project.
*Ship name: Marea or Palamida (RMRI, Constantza, Romania).
*Expedition: Monthly cruises between 1970 and 1975, 1 transect
with 5 stations, east of Constantza, sampling at the standard depths.
*Parameters: Date (year, month, day), time (hour, minute), latitude
(degrees, minutes), longitude (degrees, minutes), water depth (m),
station name, Secchi depth (m), air temperature (deg. C).
*Instruments and methods: Secchi depth is measured using standard
