Testing new technology: Underwater Hyperspectral Imager

Being able to test brand new technology is always exciting. The Ecotone Scientific UHI (Underwater Hyperspectral Imager) brought from NTNU in Norway was finished only a week before the Sonne disembarked from Guayaquil. It is the first UHI to be designed for deep sea use (6000m). Any untested equipment will present some initial challenges. During […]

Toolboxes at the seafloor

Our ROV (remotely operated vehicle) substitutes our eyes and arms at depth, but the amount of instrumentation it is able to carry (the so-called payload) is limited to the available space and weight of the payload in water since the ROV is kept buoyant by its own floatation (the yellow syntactic foam on the upper […]

How to study small organisms dwelling the seabed

Among all the amazing high-tech equipments that are being used in this SO242/2 Sonne cruise, such as the OFOS (Ocean Floor Observation System), the ROV (Remotely Operated Vehicle) and Landers measuring different environmental conditions at the seafloor, I present you a very traditional equipment used ubiquitously in deep-sea research: the Multicorer, or the MUC, as […]

Tracking the impact on Deep Sea Life

The SO242-1 cruise used an Autonomous Underwater Vehicle (AUV) to visually and acoustically inspect and map the ploughmark traces on the seafloor made by the DISCOL experiment in 1989. During SO242-2 we are using their survey data to plan a series of close up studies of the seafloor using the new Ocean Floor Observation System […]

What are you working on?

Before my shift in the lab begins I went for a walk around the ship. In the first laboratory I find Tanja and Dick (NIOZ) testing whether the algae injector of their deep-sea incubator works properly and does not release the algae before the instrument reaches the seafloor. For the test they use tea because […]

SO242-2 Back to DISCOL

With the second expedition the scientific crew on board changed, because the scientific focus is different to the first leg. This brought me on board of the “SONNE”. Here I will work as a lab assistant and I will try my best to report about the expedition in my free time. Right in the middle […]
