„Grün ist das Land, rot ist die Kant, weiß ist der Sand. Das sind die Farben von Helgoland.“

This year's spring bloom campaign on Helgoland was carried out from February 14th to May 19th. During this time, sea water samples of the “Kabeltonne”, specific coordinates between the dune and the main island, were taken daily (OMICS) or on Tuesdays and Thursdays (Glycobio). The water samples were pulled onto different pore-sized filters before shipping them to Bremen or Greifswald. However, how exactly can one imagine life and work on the rough North Sea island?

First of all, you need to know that everything on Helgoland is about the sea and the weather. Is it stormy? What is the sea state? What it the visibility? The island depends on its shipping like a fish on water. Science is no exception.

A regular day for the OMICS and Glycobio sampling starts at approximately 8:30 am. There is no need to start earlier because of the before mentioned weather dependency. AWI’s (Alfred-Wegener Institute) small science vessel, Aade, won’t arrive at a pinpointed schedule. During good weather she can be fast to collect all samples and return to the harbor by 9:00 am. But let the weather be bad, it can take until 10:00 am or later. So after we’ve prepared everything for the day, e.g. labeling all sampling tubes, filtration set-up, have have to practice patience until the ship appears on the horizon with the wanted cargo. Now, physical labor is demanded. The water cans (on Tuesdays and Thursdays approximately 120 L) are brought back to the lab with nothing but carts and muscles. A short “Moin” to the sailors followed by “Danke” and “Bis Morgen”.

Back in the laboratory, todays work can finally start. Seeing that the flow-rate is quite low, there might be an algal bloom. It’s going to be a long day. A visual check of the 3 μm filter is also a good indicator to determine whether there are many algae in the water or not. The greener the filter is, the more material there is on it. After the OMICS filters are prepared and shock frosted, we continue with the filters for subsequent cell sorting. Downstairs in the “Glycobio” laboratory, 100 L of raw seawater have to pass the different filters. This also, is going to take a while. Meanwhile, it is noon and it’s time to take a break. Since the sun is shining, we enjoy our free time at the water. It’s fairly easy to find a nice lunch because of all the local snack bars. Now all that is left to do is find a nice spot to spend the lunch break. Soon work calls again. The break passes quickly here at the ocean’s edge.

Next up for the OMICS procedure are the FISH filters, which are prepared with a formaldehyde-fixed seawater sample. But the day isn’t over yet. After all the daily samples are taken and processed, the staining of a filter section by means of DAPI and the subsequent counting of bacterial cells, still follows. As we leave the darkroom where the microscopes are located, the sun already sits deep on the horizon. Down in the basement laboratory the filtration is still ongoing, but no worries there are always the nice colleagues to talk to.

Today’s work is done and we quickly prepare everything for the next sampling day. The now empty water canisters have to go back to the ship for a new water sample and all material needs to be rinsed. This is necessary, so we receive a clean sample from tomorrow's water and prevent algae growth in the bottles. Finally, after this we’re done - it’s time to call it a day.

To be able to buy groceries at the local Edeka, the only supermarket chain on Helgoland, you have to be quick now. At 6:00 pm the shops are closed. Only restaurants and bars are still open and only during the season. It’s much nicer to spend the evening on the cliffs of the “Oberland” even if the nesting birds are quite noisy. The Lange Anna (“Tall Anna”), Helgoland’s famous sandstone stack, is dipped in the orange light of the setting sun and the wind is picking up. And so the day on Helgoland ends.
