Objectives :

In conjuction to the primary productivity measurements in the MATER project and in continuation of the 'PP cruise' series of the CINCS project (EU-MASTII/MTPI), productivity measurements were made at the two standard CINCS 'PP' stations D2 (100m depth) and D4 (540m), with the addition of the CINCS deep station D7 (MATER station MSB-2) (1600m).

Description of the field observations :

1) Water samples were collected with Niskin water bottles from the 3 stations of transect D (D2,D4,D7) of the original CINCS study area and from water column depths: 1, 5, 10, 20, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 400, 500, 700, 1000, 1200,1500m (station D2: down to 100m, station D4: down to 500m). The samples were used for:
 a) analysis of NO3, NO2, NH4, PO4, SiO2, chlorophyll-a, phaeopigments, POC, PON,
 b) primary production estimates, with the 14C in situ technique (down to 100m depth, 2replicates and 1 blank per depth),
 c) phytoplankton analysis. Samples were collected only from the primary production depth layers (station D2, d4 & D7) and preserved in Lugol.
2) With the use of a SBE-19 CTD (equipped with and photometer) profiles of conductivity, temperature, pressure and light attenuation were obtained from stations D2, D4 & D7.
3) Underwater light penetration was estimated with a Secchi disc at all 3 stations.
4) Surface irradiance was measured at all 3 stations with the use of a Bioblock Scientific LX 101 Luxmeter.
5) As part of the primary production experiments, 30 polycarbonate incubation bottles were deployed at the three stations at different depth layers, for a two hour in situ incubation. The depth layers are: 1, 5, 10, 20, 30, 40, 50, 60, 75, 100m for station D2 with the addition of 120m for stations D4 and D7.
