| Cruise Info. | |
| Ship name (ship code) | FS Meteor (06M3) |
| Cruise identifier | M42_1 |
| Cruise period | 1998-06-16 — 1998-10-26 |
| Status | Completed |
| Port of departure | Las Palmas, Spain |
| Port of return | Viana do Castelo, Portugal |
| Purpose | Research |
| Objectives | CANGO project aims:
1) To better understand the processes of physical and bio-geochemical fluxes in the eastern subtropical gyre of the North Atlantic 2) Investigation of the effects of seasonal upwelling 3) Investigation of input of Sahara dust into the ocean 4) Investigation of exchange processes between the Atlantic and Mediterranean Additional aims: 1)The exchange of longterm mooring carrying current meters and particle traps in the eastern boundary current system and at the European time series station ESTOC 2) The recovery of current meters in the Mediterranean outflow region off Portugal 3) A closed box north of the Canary Islands sampled for hydrographic, bio-geochemical and bio-optical variables 4) Vertical profiles of dissolved organic carbon taken 5) Fish levels from the Antarctic Intermediate and Mediterranean water mass levels studied 6) Contribute to all components of ESTOC 7) Meteorological station - weather consultation (issuing daily weather forecasts), meteorological observations and measurements, and determination of the net total radiation at sea. Global solar radiation and atmospheric radiation, reflected solar radiation and terrestrial surface radiation computed using numerical models measured. Direct solar radiation, sunshine duration and UV-B global radiation also measured. Docked at Las Palmas on the 25/06/98 for 1 day to unload and load equipment and exchange personnel |

| Other chemical oceanographic measurements | Quantity: number of stations = 45 Description: Down-to-bottom measurements of nutrients |
| Contamination | |
| Trace metals | Quantity: number of stations = 45 Description: Down-to-bottom measurements including aluminium, additional samples taken with in situ pumps |
| Biology and fisheries | |
| Primary productivity | Quantity: number of stations = 45 Description: Coccolithophores and diatoms taken from the upper ocean |
| Phytoplankton pigs (eg chlorophyll, fluorescence) | Quantity: number of stations = 45 Description: Down-to-bottom measurements of chlorophyll. Bio-optic variables measured to 2000m |
| Dissolved organic matter (inc DOC) | Quantity: number of stations = 45 Description: Down-to-bottom measurements of dissolved organic carbon taken with rosette |
| Phytoplankton | Description: Parallel to drifting moorings, incubation rates measured in seawater samples from upper ocean. Used to measure the growth rate of phytoplankton in water taken from traps' depth |
| Zooplankton | Description: Parallel to drifting moorings, incubation rates measured in seawater samples from upper ocean. Used to measure the grazing rates of zooplankton in water taken from traps' depth |
