Two years of continuous METOCEAN measurements at Mongstad, Norway, 2011-2013. Summary report

Abstract

As part of the design of the full-scale CO2 capture plant at Mongstad in Norway (Mongstad CCM project), NIVA conducted measurements of currents, temperature and salinity in the sea area considered for a new cooling water intake, and outlet. The measurements lasted from April 2011 to May 2013. A fixed mooring with currents meters were connected to shore via cable, for continuous data transmission and quality control. Sea temperatures were recorded by a thermistor chain laid out along the bottom, also with continuous monitoring. Additional STD-profiles were taken bimonthly. The data return was regarded as satisfactory, over-all better than 90%, with some failures of thermistors, and some false reflections of ADCP current meter beams from the sloping seabed. The present report summarizes the data collection program and the main findings, mainly based on the 24 extensive Monthly data reports and the Annual reports provided underway.
