Station M Instrument Servicing Expedition 2018 – Log 4

The cruise activities don’t end when we get back to shore. Next, comes the data analyses, interpretation, and communication through peer-reviewed research papers, social media, and press releases. The sediment traps and Sedimentation Event Sensor recorded another period during which large amounts of marine snow reached the seafloor. Interestingly, data from the Benthic Rover, time-lapse …

Contributor: University of Aveiro (Portugal) Postdoctoral Researcher Luciana Genio Knowing where and for how long the pelagic larvae of deep-sea benthic animals live in the water column is extremely important to understand how populations respond to natural (e.g., climate and food supply) and human (e.g., pollution, overfishing, mining) disturbances. On this cruise, we deployed a …

Station M Instrument Servicing Expedition 2018 – Log 2

Over the 30-year (and counting) time-series study at Station M, we have seen changes in the biological carbon pump with changing sea surface conditions along the California coast. The abyss is not the invariable environment most people once envisioned. Short-term processes and events can have major impacts on long-term patterns. Every two hours, the Sedimentation …

Station M Instrument Servicing Expedition 2018 – Log 1

The Benthic Rover is a fully autonomous underwater vehicle that collects data for the Pelagic-Benthic Coupling Lab’s studies of seafloor carbon consumption. Capable of yearlong deployments, it is the only untethered underwater rover in the world operating at abyssal depths. The Rover has transited over 11 kilometers of abyssal seafloor at 4,000 meters depth since …

Station M Instrument Servicing Expedition 2018

MBARI Expedition #451 Expedition goal: The Pelagic-Benthic Coupling Group is conducting yearly servicing of the autonomous instruments working approximately 4,000 meters deep at Station M. These instruments collect data as part of a 29-year time series study of climate influences on deep-sea carbon supply and demand. Expedition dates: October 17- 25, 2018 Ship: R/V Western …
