18.08.2016 15:23Hot summer, cold fingers (Sources & Sinks: A Tale of Coastal Biogeochemistry - BONUS COCOA)

Summer is the high time in any biological field station, buzzing of scientists on their mission to catch the growth season of nature. The common look of a summer field biologist: sweaty and sunburned, likely dressed in shorts. All of them? Well…… no. There is a small group of marine scientists that provoke puzzled looks. Their general appearance winter to summer: double soled fur boots, snow trousers and woolen head. Pale faces, cold fingers clasped around a pot of hot tea. Weirdos.

I am one of those thickly wrapped people and I am happy to announce that we are neither ill nor weirder than everyone else (at least not much); yet, working on biogeochemical processes in marine sediments means to do this under conditions as close to nature as possible with in situ temperature as a crucial factor. And as the temperature at the bottom of the sea is usually cold, so it is in the climate controlled lab.


Summer at Tvärminne Zoological Station: while surface waters warm up (upper pics), bottom waters stay cold - so does my lab (lower pics).

Now you may say: “Come on, you are not working on open ocean sediments! Get a grip - you are working at the coast, the water column is much shallower there, shouldn´t also the bottom water warm up during summer at only 30 m water depth?”

Thanks to stratification of the water column: not much! While the water column in winter and spring is mixed from surface to bottom due to colder air and thus water temperatures and frequent storms, it becomes stratified when increasing air temperatures warm up the surface waters. Warmer water has a lower density than colder water, resulting in a layering of the water column with warm, light surface waters on top of cold, heavy bottom waters. These layers don´t mix without strong external forcing (like a heavy summer storm), which means…..it stays chilly at the bottom of the sea.

You can follow the establishment of this year´s summer stratification at Storfjärden (33m), Finnish coast in our monthly salinity and temperature profiles (data: group Hietanen, unpublished).


In April, the water column is still roughly mixed with only a slight difference in temperature between sea surface and bottom (brrrr, 1.5°C ....). Profiles are taken with a CTD probe (conductivity-temperature-depth).


1 month later in May, surface waters are already 8°C and the water column is layered into a warm surface and a cold bottom layer. This bottom layer becomes even colder one month later, while surface waters become warmer and warmer. Now, in August, bottom waters had reached about 5°C, which felt nearly warm in the climate control lab.

Let´s see how it will be in September and October: a cooling of air temperature will also cool surface waters, weaken the stratification and with the help of a storm break the layering, so that water masses mix again. Maybe some time in autumn I might be able to take off my woolen head.
