Temperature, salinity and oxygen measurements

NOTE: INTERNET EXPLORER MAY REDUCE IMAGE QUALITY. USE ANOTHER BROWSER IF POSSIBLE

Below you can see the most recent measurement made by our mooring in the Byfjorden. The instruments on the mooring continously measure temperature, salinity and oxygen concentrations at their depth. Approximately every fourth hour the gathered data is transmitted and automatically published here without delay. The graph displays temperature in degrees Celsius (green), salinity in salinity units (cyan), density (black) and dissolved oxygen in micromoles per litre (red line). In addition to each parameter, the water column on 16 June 2011 is shown as dashed lines. Click on image for a larger version.

The contour graphs below show the past four weeks measurements. The upper figure show temperature in degrees Celsius salinity. The lower figure show density and dissolved oxygen. On the right hand side you will find the colour bar for the graphs. The horizontal dashed line in the oxygen graph indicate the border for anoxic water. Anoxic waters have a concentration of dissolved oxygen of 0 micromoles of oxygen per litre. Please note that the smaller yellow lines on the sides of all three graphs denote depths of the instruments. Click on the image for a larger version.
