Today's Atmospheric/Ocean Weather

Morning

Evening

ATMOSPHERE -- Today was windy again, but the wind rotated around from the southwest in the morning, to the northwest in the evening. Temperatures were very warm today, with a high of 86 and a low of 72 F. The weak cold front from the west is passing through which should cause the winds over the next couple of days to be mostly northeasterly, which are downwelling favorable.

Plots of today's weather data from the Field Station are shown below.

OCEAN -- The upwelling hit the surface today, with coastal ocean temps dropping to the low 60s in many areas north and south of our research site. Today, we have an addition to our ocean data as the first ships gathered data for our month long research project. CODAR compliments this ship data in showing the offshore currents, but unfortunately, it was too cloudy to get good satellite imagery. Maybe tomorrow, but, TODAY, IT BEGINS.....

ADCP and CTD data collected from the R/V Caleta reveal some very interesting hydrodynamic features above topographic irregularities on the S1 line. Isotherms seem to dip sharply just offshore the location of a sand trough and along-shore currents are accelerated near the ridges of these topographic features. The data from the flourometer indicates that the locations of the troughs coincide with increased biological activity. Yesterday's upwelling favorable winds have begun to veer towards the northeast and east.
