I-COOL

The sea surface temperature is warmer in earlier days and suddenly gets colder as it gets into mid-October.

The halo cline is at about 14 meters in depth. The farther the glider goes off coast, the more salty it is farther out. The closer the glider is to the coast, the less salty it is. Highest salinity is farther out at 32 PSU at the depth of 17 meters. Least salinity is closer at 29.7 PSU at the depth of .5 meters.

This graph is of the temperature recorded by the glider RU 15. It shows that the temperature at a higher depth is warmer than the water at lower depths due to density. Cold water is more dense than warm water so it is at the bottom. The sun heats water at the top and since it is warmer than the water at the bottom, so it stays up top. The thermocline is at about 13 meters.

The temperature near the surface is much warmer, until October 17. It could be possible that there was a storm that chilled the surface water temperature. Or that the glider is just moving into deeper colder water. But the most reasonable explanation for the temperature change is a cold rain storm.

The temperature cline in this graph indicates that as depth increases temperature generally decreases; the change in uniform temperature implies that cool water was added to the water column, so perhaps a storm came in and dropped some cold, fresh water on the surface, and/or wind mixed the existing warm and cool water.

As the depth of the ocean increases, the salinity of the seawater increases.  Towards the top of the ocean, at the beginning of deployment, the salinity level is much lower than a few days later.  The halo cline increases as the depth of the ocean increases and as the days pass.

This map shows the glider RU07's movement from one dot to the next.

This graph shows the current water temperature. The warmest water is at the surface at a temperature of about 18.5 to 19 degrees Celsius. Deeper down the water gets progressively colder until it reaches around 17 degrees Celsius.

This image shows that the salinity of the water increases as depth increases.

This graph of density shows that denser water can be found deeper in the ocean. The density ranges from 1019 kg m-3 at the surface to 1022.5 kg m-3 around 25 meters down.

Finally, this graph shows the amount of dissolved oxygen in the water. The amount of oxygen stays relatively high until about 15 meters underwater, then the concentration of oxygen quickly decreases.

Since I can't figure out how to put words between the pictures at the moment, I'll describe the pictures here.  The first picture should be telling the movement of the glider, from its current position to its final destination.  It seems to be awfully close to its destination, just a bit northeast of it (assuming green is where it currently is and red is the destination).   As for all the graphs, (going from top to bottom), chlorophyll has the highest concentration at the depth of 22-25 feet.  I guess the phytoplankton like their water a bit saltier and colder than normal plants, or can only tolerate certain conditions.  After all, there is a sudden increase of chlorophyll from the depths of 20-22.   Of course, water density increases as depth increases, due to pressure that their comrades on top are exerting, and the chart shows the steady increase.  Meanwhile, salinity increases with water density, as the salt seems to refuse to dissolve evenly.  Finally, water temperatures decrease as depth increases since the deeper the water is, the farther away it is from the heat source, the sun.  Water that is cold happens to be denser than warm water, which would explain why cold water is on the bottom instead of the top.

This is a really small picture. . . but the glider is going south after going right. 2011-10-10 07:18 - 2011-10-12 00:20 GMT

Water temperature is constant. There are no sudden drops. There are drops closer to the bottom but that's normal. Warmest so far would be 19.7 degrees.

Salinity is lower at top than getting closer to t bottom. It seems constant along the way. Highest would be about 31.5 psu.

Density, like the salinity, gets more dense when getting near the bottom. Maybe the pressure affects the salinity of water. Anyway, highest density is 1022.9 kg/m^-3.

Chlorophyll is higher near the bottom. Maybe it works in higher salinity. Highest is more than 5 micrograms/liter!
