| BGODC | Konsulov Asen Stefanov | 27 | stations | B02 Phytoplankton pigments (e.g. chlorophyll, fluorescence) |
The samples for chlorophyll a were filtered through vacuum pump (Sartorius), glass fibber filters (GF/F). Chlorophyll a was measured spectrophotometrically in acetone extracts (Edler, 1979). Samples-105 | no |
| BGODC | Konsulov Asen Stefanov | 27 | stations | B08 Phytoplankton |
Phytoplancton samples were preserved by formaldehyde (4%) or glutaraldechid and concentrated according to Uternol (1958)/Edler (1979). The indentification of species and cell counting was done under light system microscope (Olimpus BX 41) in Palmer Maloney countingh chamber, by the protocol of Suornia (1978). Samples-110 | no |
| BGODC | Konsulov Asen Stefanov | 26 | stations | B09 Zooplankton |
Zooplancton samples were collected with vertical closing plancton net "Jeddy" - 36˚cm. diameter, and 150˚μm mesh size. The species abundance was accomplished according to Dimov's method (Dimov, I., 1959). Individual standard species weights were used for calculations of biomass in milligrams per cubic meter (Petipa, 1959). Samples-78 | no |
| BGODC | Konsulov Asen Stefanov | 9 | stations | B13 Eggs/larvae |
Ichthyoplankton, Bongo net, mesh size ? 300 μi. Samples-9 | no |
| BGODC | Konsulov Asen Stefanov | 6 | stations | B18 Zoobenthos |
Van Veen grab with sampling area 0.1˚m² was employed for collection of quantitative macrozoobententhic samples. The samples were checked for adequacy ? the grab should penetrate to a digging depth of at least 10 cm. (20 better) and contain about 4l of sediment (Gray et al 1992). Samples-8 | no |
| BGODC | Krusteva Snejana | 15 | stations | H09 Water bottle stations |
Water bottle stations, Rosetta up casts. | no |
| BGODC | Krusteva Snejana | 35 | stations | H10 CTD-Stations |
SBE 911 plus CTD System (enhanced SBE 9/11), Temperature [ ITS-90, deg.C?] vertical profiles, Salinity [PSU], vertical profiles | no |
| BGODC | Krustev Anton I. | 15 | stations | H21 Oxygen |
Winkler method, samples-58 | no |
| BGODC | Krustev Anton I. | 15 | stations | H22 Phosphates |
Molybdate method with reductant ascorbic acid, samples-58 | no |
| BGODC | Krustev Anton I. | 15 | stations | H24 Nitrates |
Determination of nitrates by Grasshoff method after reduction with Cadmium, samples-58 | no |
| BGODC | Krustev Anton I. | 15 | stations | H25 Nitrites |
Grasshoff method, samples-58 | no |
| BGODC | Krustev Anton I. | 15 | stations | H26 Silicates |
Molybdate method (Karoleff) by reduction with ascorbic acid, photokolorimeter KFK, samples-58 | no |
| BGODC | Krustev Anton I. | 15 | stations | H28 PH |
Equipment: pH meter "Hanna", kolorimeter KFK, samples-59 | no |
