Sampling the invisible
Microbes play many vital roles by physically and chemically changing their surroundings: they consume and produce a diverse range of organic and inorganic materials, provide food for other organisms, and drive biogeochemical cycles on a global scale.

Station 9
It was 1430 hours when the drone took off, loaded with an array of instruments designed to gather data for a period of three hours. “Now I’m excited!” said Chris Zappa, whose working group is in charge of modelling the factors governing air-water gas transfer in physically complex ocean systems.

A little goes a long way
I am one half of the trace element sampling team – mentioned in an earlier blog post as the ‘Dust People.’ Together with Bill Landing from Florida State University, we are collecting a range of samples (aerosols, a.k.a. dust; rain; sea-surface microlayer; and underlying water from about 30 cm depth) for the determination of trace elements.

No time to lose
It could be assumed that given the intensity of operations in this expedition, the thought of a five-day transit through calm waters would be warmly welcomed. The scientists would perhaps take advantage of the extra time by answering neglected emails, organizing their paperwork, or cleaning a few of their instruments; but mostly, many would expect them to rest, regain their energy and acclimatize to Falkor’s newfound rocking and rolling.
Growth through experience
I am a second-year Phd student in the field of marine environmental science in the University of Oldenburg in Germany. My interest lies in the role of microbes within the sea surface microlayer, how they are adapted to this very special habitat, and their potential to influence air-sea gas exchange processes.

Sea-Surface Microlayer Week 2 Video Update
Crew and researchers give a look into their roles in this Study of the Sea-Surface Microlayer and Air-Sea Boundary research cruise. At sea and on the ship, everyone has tasks that lead to the gathering of scientific data in this expedition.
