By Naomi Krauzig (GEOMAR) As the research vessel METEOR heads north toward Germany, the CTD Lab has become quiet. For the past four weeks, the CTD rosette (named after the three core variables it measures: conductivity, temperature, and depth) has been one of the busiest instruments on board. Day and night, it disappeared beneath the […]
Counting Snowflakes in the Darkness of the Deep Ocean
By Joelle Habib (Laboratoire d’Océanographie Villefranche) When I was a kid, I wanted to be a photographer. I still do, actually. But somewhere along the way, science intervened, and it gave me something I never expected: the chance to be an underwater photographer. Not the National Geographic kind who chases polar bears or waits weeks […]
Ocean of Data
By Qi-Fan Wu (Niels Bohr Institutet, University of Copenhagen) In 1943, when Warren McCulloch and Walter Pitts showed that neurons could be represented by simple electrical circuits, they laid the first foundation for machines that could learn, adapt, and predict. In 2023, when ChatGPT became widely used, my Introduction to Python professor found that it […]
How to thrive on a German ship (by and for non-Germans)
By Nathalie Rodríguez Lara (GEOMAR), Federico Scarscelli (GEOMAR), Ajit Subramanian (LDEO), Qi-fan Wu (University of Copenhagen), Eduardo Lima (UFPE), Herbert Barbosa (UFPE), Joelle Habib (LOV) and Zengchao Xu (GEOMAR) So, you have been invited to participate in an oceanographic research vessel? Congrats! Oh, it’s German… well. Here are some tips that will be especially useful […]
What can PIES tell us about the current system?
By Tina Hans (GEOMAR) One main objective of the cruise is to investigate the large-scale ocean currents in the tropical Atlantic. For that purpose, we are maintaining several long-term observatories at the seafloor and in the water column. Additional to the moorings which have been described in the previous blog “Keeping the record alive”, we […]
Cloud: The Pearl on the Crown
By Qi-Fan Wu (Niels Bohr Institutet, University of Copenhagen) During our journey, we saw many beautiful cloud patterns while looking outside the METEOR! Even though people do not always pay attention to them, clouds are among the most visible elements of the sky and naturally form part of our everyday background. And when we sailed […]
Keeping the Record Alive: Long-Term Ocean Observations in the Tropical Atlantic
By Naomi Krauzig (GEOMAR) One of the most rewarding aspects of M219 has been contributing to the maintenance of the long-term GEOMAR mooring arrays that quietly monitor the tropical Atlantic year after year. While CTD/LADCP casts and other shipboard measurements provide invaluable snapshots of the ocean, these anchored instruments provide something that cannot be obtained […]
30 Days at Sea, 30 Ways to Make Potatoes
By Joelle Habib (Laboratoire d’Océanographie Villefranche) When you go on a scientific cruise, you always think about the instruments you’re going to deploy, the great data you’re going to acquire, or the experiments you’ll conduct. What you almost always forget is the small thing that isn’t actually small at all: food. And how are you […]

Schiffe – aber mit erneuerbaren Energien: Geht das?
Autor*in: benthos531 Schiffe – aber mit erneuerbaren Energien: Geht das? Durch den Klimawandel wird unsere Erde immer stärker geschädigt. Da diese Erwärmung des Klimas hauptsächlich anthropogen ist, ist es die Verantwortung der Menschheit, sich um dieses Problem zu kümmern. Doch wo setzt man an? Ein guter Anfang wäre es, erneuerbare Energien auszubauen und diese vor […]
Where the sky meets the ocean
By Leonie Jaeger (ICBM Oldenburg) The ocean is the dominant climate regulator of our Earth. I am on board the RV Meteor to conduct measurements that helps us better understand the critical processes at the interface between the atmosphere and the ocean. The focus of these measurements is heat and freshwater fluxes, two key drivers […]
