STR Management has moved to MFP

The US Academic Research Fleet is moving to Marine Facilities Planning (MFP) for scheduling initially and eventually cruise planning.

For all NEW or RESUBMITTED Projects/Ship Time Requests, go to https://mfp.us and create a new SME. Some STRs for projects starting in 2022 and beyond have already been moved to Marine Facilities Planning (mfp.us). Check your MFP Science Portal for any projects that might already be moved. If you need to make edits to projects that begin in 2022 and beyond, please contact mfp@unols.org for assistance. Be sure to indicate the Project and STR IDs that you would like to edit. For more information on getting into MFP, see the More Information button below.

Project Title: NGOMEX 2009 - Mechanisms Controlling Hypoxia: Integrated Causal Modeling Project Status: Submitted
Principal Investigator: Steven F. DiMarco, TAMU_CS Project Institution: TAMU_Galv
Project ID: 103119 Version #: 1
Date Submitted: 9/7/2011 4:11:00 PM Created By: Antonietta Quigg

Funding Agencies: NOAA - NOS-NCCOS-2009-2001466 - Funded
Summary of Field Work: The physical and biogeochemical processes that control and maintain the hypoxic zone in the northern Gulf of Mexico are complex and their relative strengths are known to vary temporally and spatially at many scales. Although close to the Mississippi River Delta, the mechanisms that maintain and sustain the hypoxia are mostly driven by biological processes, further downstream the dominant controlling processes are mostly physical as currents and winds combine to break down the vertical stratification necessary to sustain the low dissolved oxygen. Because the eastern region of the shelf, between 91°W and 89°W, is almost always hypoxic in mid-summer, it is variability of the western region, between 91°W, the Texas border and west, that largely controls the total size of the hypoxic area in a given year. Investigations of water quality data from coastal Texas have shown that hypoxic conditions frequently occur there and with variable driving factors. Therefore, understanding the interactions of the physical, biological, and geochemical processes and their variability throughout the shelf is critical for a comprehensive description of the mechanisms that control hypoxia.

A comprehensive, integrated, and multidisciplinary study of the Texas-Louisiana Shelf is proposed that includes multidisciplinary moored time-series observations (two real-time reporting and one autonomous/internally recording), two seasonal interdisciplinary process cruises near the mooring locations, two summertime shelf-wide surveys using a undulating towed sensor (to determine spatial extent of hypoxia), and remote sensing observations. The field component is designed to complement, and provide rates and other parameters necessary for the initiation, control, and skill assessment of a realistic coupled three-dimensional hydrodyamic-biological-geochemical-sediment numerical modeling and statistical (multivariate) modeling elements. A diagenetic model of the upper seabed, sediment resuspension, and surface gravity waves will be coupled to this model as previous studies have indicated that seabed processes can impact oxygen consumption and contribute to the variability of the hypoxic area.

The principal scientific objective of this study is to build upon a previously funded (2003-2009) and proven realistic coupled hydrodyamic-biological-geochemical-sediment numerical model of the northern Gulf of Mexico that is capable of resolving the dominant oceanographic processes that control the timing, duration, and severity of hypoxia of the region. Observations and modeling activities will be coordinated with relevant and existing federal and state funded operational and regional efforts and other regional investigators through active data exchange and participation and sample collection on appropriate and available cruises of opportunity.

Repeating Cruise?

Yes Interval: 4 months # of Cruises: 2

Description of Repeating cruise requirements:
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
we would like these dates as they coincide with dates of cruises conducted in 2010 and 2011. in addition, we would like these dates are they reflect periods when typically there is no hypoxia (April) and hypoxia (August) in the Gulf. Given the nature of the program, which is to study mechanisms controlling hypoxia these choices are key.

lastly, these dates work for the persons who will be chief scientists and executing the science during the cruises
