Die Illusion von Neutralität in der Wissenschaft

Am 24. September fand ein deutschlandweiter Klimastreik statt, anlässlich der anstehenden Bundestagswahl. Im Rahmen des Streiks und der Wahl, wurde in wissenschaftlichen Kreisen intensiv diskutiert, inwieweit man sich denn nun thematisch politisch positionieren dürfe.Die Wahl war entscheidend. Sie würde bestimmen, welche Parteien die letzte Entscheidungsgewalt bekämen, noch Maßnahmen zu ergreifen, die zumindest Deutschlands Anteil am […]

Flowing Adventure

Throughout the past few weeks of the mesocosm experiment I have been having these recurring dreams in which I was a traveling microalga. My life as a dinoflagellate named Scrippsiella had been quite ordinary before I was collected from one of the mesocosms. Floating freely in the water column, I had been capturing photons from […]

Nutrients – the base of every food web

Nutrients are an essential part of every food web. Every organism on Earth needs nutrition to build up amino acids, proteins, enzymes etc. It is necessary to maintain the integrity of every cell. In the ocean, there are three major inorganic nutrients, which are important for marine primary production, but also often limited in supply: […]

M176/2 Ba isotopes and Rare Earth Elements in the Rainbow Plume!

Photo 1: MUC camera capturing the strong particle plume (Photo Z Zhang).

“How to make a group of scientists very happy and super excited?” “Oh smoke!” On the 5th working day, we were at the location near Rainbow hydrothermal vent. From the camera attached to the multicorer, we saw very strong plume and smoke at about 2000 m depth. And this, charged a whole room of scientists […]

Diving at the mesocosms #2: Cleaner fishes

Once the mesocosm experiment sails smoothly (this rarely happens, but astonishingly, this time it’s the case à knock on wood), most of the divers can concentrate on the real life as a scientist above water in their grey labs and offices – the colorful, exciting harbor life (mentioned in the first post) becoming only a […]

Performing (Oxygen) MAGIC!

Making oxygen (O2) magic just looks cool, but it is also fascinating and highly relevant. This analysis looks into the amount of oxygen that exists in a water sample. As we all know, oxygen is essential for most living organisms. All of them breath it in, and some of them actually release it back and […]

M176/2 Time-series study of biological N2 fixation in the North Atlantic

It is a great honor to join the scientific cruise M176/2, a part of the International GEOTRACES Program as a process study. The aim of this cruise is to conduct a detailed geochemical study of the hydrothermal plume at deep (~2500m) close to the sea floor at the Rainbow Vent in the North Atlantic. But […]
