Dutch JGOFS - Underway measurements during the North Atlantic Pilot Project (NAPP)
Listed in NASA Earthdata CMR
The North Atlantic Pilot Project (NAPP), also known as the North Atlantic Bloom Experiment (NABE), was the first field work of JGOFS (Joint Global Ocean Flux Study) and it served as pilot study for the proposed North Atlantic Process Study.
Description
Six countries participated in this study: Canada, France, Germany, The Netherlands, UK and USA The Netherlands contributed to NAPP with four cruises on board R.V. Tyro: 1. Leg 1, 31 July-11 September 1989 (Upper Ocean Processes) 2.
Leg 2, 13-28 September 1989 (Benthic Processes) 3. Leg 3, 17 April-31 May 1990 (Upper Ocean Processes) 4. Leg 4, 2-29 June 1990 (Benthic Processes) The sea surface conductivity was recorded continuously by a Seabird thermo-salinograph which was flushed by means of a pump-system.

The salinity of surface waters was recorded by a Seabird thermosalinograph that was flushed by means of the deckwash pump. Temperature was measured with a calibrated Pt-100 resistance which was mounted in the main cooling water inlet. Temperature and flourescence has been recorded continuously with a strip chart and with a data acquisition computer from Madeira and on.
A special interface card combined with the data acquisition module gave one minute measurements and registrations of chlorophyll a, temperature, date, time, position, heading and speed. Whenever possible TCO2 measurements of the surface waters have been made with an interval of approximately 6 minutes. After the cruise these two separate datasets will be combined into a final sea surface data base.
The fluorescence meter is not calibrated at the NIOZ. Raw data files were continuously saved. For calibration of the (new) TCO2 online measurements samples were taken regularly with either the rubber boat of if convenient with the CTD rosette sampler.
Their appears to be a strong diurnal rhythm in the TCO2 data.
