Mulit year SCANFISH data
Generated from SCANFISH .xlsx files contributed by Jamie Pierson
Scanfish CTD data were processed using the Sea-Bird Data Processing routines to filter, align, and bin-average data. In 2003 and 2004 dissolved oxygen was calibrated using a two step process. First, the shipboard CTD data was calibrated to niskin bottle samples using a Winkler titration performed in the lab of Nancy Rabalais. Then the Scanfish CTD were cross-calibrated to the shipboard CTD. In subsequent years, the shipboard CTD was pre-calibrated before our cruises, and we cross-calibrated the shipboard and Scanfish CTDs. The calibration between the Scanfish and shipboard CTDs was done in excel using a regression analysis to compare data from the same depths between the two instruments.

| Generic Instrument Name | Scanfish |
| Generic Instrument Description | The Scanfish is a remotely operated, towed, undulating vehicle system designed for collecting 3D profile data of the water column. It includes a Conductivity, Temperature, Depth (CTD) profiler as part of the instrument package. The Scanfish housing has fins to allow it to dive and rise, an altimeter to determine the depth of the unit, a pump that moves water through the system and a data cable that reports data back to the ship as the fish is being towed through the water behind the vessel. The Scanfish can be configured with additional sensors, e.g. fluorometer. |

Gulf of Mexico - Deepwater Horizon Oil Spill (GoMX - DHOS)
GOM - Broader Impacts
The need to understand the impact of this largest oil spill to date on ecosystems and biochemical cycling is self evident. The consequences of the disaster and accompanying clean up measures (e.g. the distribution of dispersants) need to be evaluated to guide further mediating measures and to develop and improve responses to similar disasters in the future. Would it be advantageous if such oil aggregates sink, or should it rather remain suspended? Possibly measures can be developed to enhance sinking or suspension (e.g. addition of ballast minerals) once we understand their current formation and fate. Understanding the particle dynamics following the input of large amounts of oil and dispersants into the water is a prerequisite to develop response strategies for now and in the future.
