IORS | Marasovic Ivona | 6 | stations | B08 Phytoplankton |
UTHERMOHL method of identification and calculating of phytoplankton (Utermohl,1958), | no |
IORS | Krstulovic Nada | 4 | stations | B09 Zooplankton |
"Niskin" bottle sampling (microzooplankton), | no |
IORS | Krstulovic Nada | 4 | stations | B09 Zooplankton |
Net sampling (mesozooplankton) 125 micrometers, Nansen net, mesh net 125 micrometers | no |
IORS | Dadic Valdo | 2 | stations | D01 Current meters |
Aanderaa RCM4S, | no |
IORS | Antolic Boris | 6 | stations | H09 Water bottle stations |
Nansen water bottle, two liters volumen | no |
IORS | Grbec Branka | 6 | stations | H10 CTD-Stations |
Ocean seven 316 probe, Pressure range 1500 meter. S.N. 0797032 | no |
IORS | Morovic Mira | 6 | stations | H16 Transparency (e.g. transmissometer) |
Sechi disc (white, 30cm), White sechi disk, 30cm | no |
IORS | Kuspilic Grozdan | 6 | stations | H21 Oxygen |
Winkler titration, Oxygen is determined at standard oceanographic depths. By the Winkler method oxygen isexpressed as ml/L. If temperature and salinity is known, oxygen saturation can be calculated. | no |
IORS | Kuspilic Grozdan | 6 | stations | H22 Phosphates |
Nutrient (phosphates), Working equipment: AutoAnalyzer Bran Luebbe AA3 , Following the method of Murphy and Riley, this automated procedure for the determination of orthophosphate is based on the colorimetric method in which a blue color is formed by the reaction of orthophosphate, molybdate ion and antimony ion followed by the reduction with ascorbic acid at an ph<1. | no |
IORS | Kuspilic Grozdan | 6 | stations | H23 Total - P |
Nutrients (total - P),Working equipment: AutoAnalyzer Bran Luebbe AA3,After oxidation of water sample in the UV oxidation unit, the sample has been analysed by the same procedure described as phosphorusly analysis. | no |
IORS | Kuspilic Grozdan | 6 | stations | H24 Nitrates |
Nutrient (nitrates),Working equipment: AutoAnalyzer Bran Luebbe AA3,This automated procedure for the determination of nitrate uses the procedure whereby nitrate is reduced to nitrite by a copper-cadmium reductor column. The nitrite then reacts with sulfanilamide under acidic conditions to form a diazo compound. This compound then couples with N-1-naphthylethylenediamine dihydrochloride to form a p | no |
IORS | Kuspilic Grozdan | 6 | stations | H25 Nitrites |
Nutrient (nitrites), Working equipment: AutoAnalyzer Bran Luebbe AA3,This automated procedure for the determination of nitrite uses the procedure whereby the nitrite ion reacts with sulfanilamide under acidic conditions to form a diazo compound. This compound then couples with N-1-naphthylethylenediamine dihydrochloride to form a reddish-purple azo dye. | no |
IORS | Kuspilic Grozdan | 6 | stations | H26 Silicates |
Nutrient (silicates),Working equipment: AutoAnalyzer Bran Luebbe AA3,This automated procedure for the determination of soluble silicates is based on the reduction of silico-molybdate in acidic solution to molybdenum blue by ascorbic acid. Oxalic acid is introduced to the sample stream before the addition of ascorbic acid to minimize interference from phosphates. | no |
IORS | Kuspilic Grozdan | 6 | stations | H75 Total-N |
Nutrients (total - N),Working equipment: AutoAnalyzer Bran Luebbe AA3,After oxidation of water sample in the UV oxidation unit, the sample has been analysed by the same procedure described as nitrogen analysis. | no |
IORS | Kuspilic Grozdan | 6 | stations | H76 Ammonia |
Nutrient (ammonia),Working equipment: AutoAnalyzer Bran Luebbe AA3, This method uses the Berthelot reaction, in which a blue-green coloured complex is formed. A complexing agent is used to prevent the precipitation of calcium and magnesium hydroxsides. Sodium nitroprusside is used to enhance the sensitivity. | no |
