The R/V Knorr in "warm" weather conditions. (Christopher Griner©WHOI)
Meteorological conditions during the 1998 cruise were more variable than during the 1997 cruise. In 1997 a virtually continuous "cold air outbreak" situation brought cold, dry air masses over the Labrador Sea. In 1998, conditions were more typical, with different types of air masses affecting the weather and surface fluxes experienced during the cruise. Southerly air flow periods brought relatively warm and moist air to the region which decreased the turbulent latent and sensible heat loss from the ocean. There were cold air outbreak periods with weather and flux conditions similar to 1997, except lasting only a day or so. More overview information is available.
This site shows meteorological data, including surface fluxes, from the 1998 Knorr cruise of the Labrador Sea Deep Convection Experiment. Similar to the 1997 pages, here you can find links to some plots of surface meteorology variables and descriptions of available data sets for the 1998 cruise.
Following are links to some plots of meteorological parameters and other quantities measured during the cruise. These may be freely copied, but please contact Peter Guest if the plots are used in any publication or presentation. This is to insure that you are aware of any changes or problems discovered with the data. Make sure other people who receive anything here are also aware of this request.
