BioChem: Diatom and dinoflagellate profiles collected in Bedford Basin, January to October 1967 (OBIS Canada)Entry ID: OBIS.BioChem_BB1967_FRB_R120
Abstract: An oceanographic station was established at a fixed navigational buoy in Bedford Basin, Nova Scotia, Canada. This station was occupied a total of 46 times during 1967 at approximately weekly intervals. The sampling program was carried out with the purpose of monitoring the physical and biological oceanographic changes in the Basin seasonally and to shed more light on the exchange of the water ... within the Basin with the coastal waters.
As part of the sampling program, two water bottle casts were made using Knudsen water bottles fitted with two Richter and Wiese or Yoshino protected thermometers. Samples were taken at 5, 10, 20, 30, 50 and 60 metres depth. A surface sample was taken with a bucket.
A 1, 10, or 25 ml aliquot of the Lugol preserved sample was drawn depending upon phytoplankton concentration and the cells were counted using an inverted plankton microscope (Utermohl 1936). The corresponding factor was then applied to the diatom and dinoflagellate counts to obtain the counts per litre.
The OBIS dataset contains a subset of the published data - it contains the abundance distribution information for the dinoflagellates and diatoms.
