Fresh off RV Alkor and back in Kiel, I’m excited to share another blog post about our scientific research cruise AL630. I’d like to tell you something about one of the sampling methods that we used during the cruise. To track the daily movements of zooplankton in the water column at our station BB23 – […]
From Models to Research Cruises, an exciting journey: Eggs and larvae finding their way through the Baltic Sea!
Hello blog readers, It’s another exciting day aboard the ALKOR630 cruise! The sun is rising, and the bongo nets and water samplers are ready to go. Greetings from Station BB23—one of the most sampled and ecologically important hotspots for phytoplankton, copepods, and fish eggs/larvae. Today, we’re exploring a technique called Lagrangian particle tracking (LPT)—a powerful method for tracing the path of a water parcel in […]
AL630 successfully completed, but…
Hi readers, We have successfully completed cruise AL630 on April 16, 2025. After one day without work due to strong northwesterly winds 7-8 Beaufort, during which we entered Rönne harbor on Bornholm Island, the last 5 days of the cruise were packed with work, running continuously in 24-operations in shift work. We therefore were not […]
Flatfish!
Hello again from Alkor! We are on day 9 of our research cruise in the Baltic Sea and today we would like to tell you more about the flatfish world. But let’s start from the beginning. Have you heard about metamorphosis before? It describes the transformation of a body form and structure after hatching, just […]
AL630 now posting from the Baltic Sea!
Hello from Bornholm Basin in the central Baltic Sea! With a team of 12 scientists and 11 permanent crew, we are currently operating in Baltic waters (see Figure 1) with research vessel Alkor to improve understanding of this beautiful but also heavily impacted and rapidly changing system. For this purpose, we measure physical parameters (temperature, […]
Fish larvae
The sorting and sampling of fish larvae is one of the main tasks on our research cruises. Every year we cover a specific grid of 45 stations in the Bornholm Basin and since last year we also sample 35 stations on a grid in the western Baltic Sea. On each of these stations, sampling consists […]
Sampling the dark hours
Time at sea is limited and thus precious and there is so much to be done on a scientific cruise. To get the best possible snapshot of life in the Baltic Sea during our 12-day journey, we therefore try to sample as many locations as we can along the way to increase the resolution of […]
AL592 now posting from the Baltic Sea!
Hello from Bornholm Basin in the central Baltic Sea! With a team of 12 scientists and 11 permanent crew, we are currently operating in Baltic waters with research vessel Alkor to improve understanding of this beautiful but also heavily impacted and rapidly changing system. For this purpose, we measure physical and chemical parameters (temperature, salinity […]
Alkor Cruise 563: What are we doing, and why?
It was a nice and sunny day, like most of our days on the Alkor, the research vessel of our cruise. Steady noise coming from the winch and anticipating buzz, which surrounded a group of students with safety boots and helmets, filled the air. Once the upcoming net broke the water surface and got „gehievt“ […]
Science, the Sea, and Finding My Sea Legs
Back in October of 2020, deciding to move to a new country where I didn’t speak or understand the language at the height of a worldwide pandemic to pursue MSc. Biological Oceanography was a challenge I never thought I could overcome, but here we are in September 2021! Truth be told, two semesters of just […]
