1 Gulf of Mexico Hypoxia Monitoring Implementation Plan Alan Lewitus NOAA/NOS/NCCOS Center for Sponsored Coastal Ocean Research GCOOS Board of Directors Meeting 19 Aug 2008
2 Management Driver: Action Plans for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico Future Rounds of Adaptive Management CENR State-ofknowledge report Hypoxia Action Plan EPA Science Advisory Board Hypoxia Report Gulf Hypoxia Action Plan 2
3 2001 & 2008 Action Plan Coastal Goal Reduce the 5-year running average of the hypoxic zone areal extent to less than 5000 km 2 (1928 mi 2 ) by the year (by reducing) the annual discharge of nitrogen into the Gulf. [2001] (by reducing) the annual discharge of nitrogen and phosphorus into the Gulf. [2008] 3
4 Coastal Goal Metric
5 Need for Extension of Monitoring Action Plan (2001): greatly expand the long-term monitoring program for the hypoxic zone, including greater temporal and spatial data collection, measurements of macro-nutrient and micronutrient concentrations, and hypoxia Monitoring, Modeling, and Research Workgroup Report (MMR, 2004): (monitoring) efforts need to be increased in frequency, at a minimum monthly from May through September. To develop a more complete understanding of ecosystem dynamics, selected sites should be monitored yearround. The spatial boundaries of some of these existing monitoring efforts should be expanded to collect data for defining boundary conditions in modeling efforts."
6 Summit on Gulf Hypoxic Zone Monitoring Summit on Long-Term Monitoring of the Gulf of Mexico Hypoxic Zone: Developing the Implementation Plan for an Operational Observation System
7 Summit Outcomes White Paper to Improve Monitoring of the Gulf of Mexico Hypoxic Zone in Support of the Hypoxia Task Force s Coastal Goal White Paper: Compilation of a Hypoxia Data Inventory Gulf of Mexico Hypoxia Monitoring Implementation Plan
8 Need for Extension of Monitoring 2008 Gulf Hypoxia Action Plan Action 9: Continue to reduce uncertainty about the relationship between N and P loads and the formation, extent, duration, and severity of the hypoxic zone, to best monitor progress toward, and inform adaptive management of the Coastal Goal
9 Critical Needs for Action 9 A long-term and sustainable hypoxic zone monitoring program, with adequate spatial and temporal coverage. Increase number of shelf-wide surveys with greater area surveyed Additional in situ platform-based continuous monitoring devices (observing systems) Mechanism to transition monitoring from a research to an operational framework Improved predictive modeling capabilities
10 Coastal Goal Metric Mid-summer Annual Assessment of Hypoxic Zone Areal Extent Dead Zone Area (sq mi) 9,000 8,000 7,000 6,000 5,000 4,000 3,000 2,000 1, Long-Term Average Action Plan Goal Year Average Data Source: NOAA/N. Rabalais, LUMCON
11 Management Drivers Priority 1 (Core System Requirements) Provide sufficient monitoring data to ensure that management is adequately informed in efforts to achieve the Coastal Goal of the Action Plan
12 Management Drivers Priority 2 Assess annual changes in the magnitude, seasonality, duration, and distribution of hypoxia, and relate these to management activities that affect nutrient loading and other influences on hypoxia
13 Management Drivers Priority 3 Provide adequate data for predictive models to develop accurate forecasts of hypoxia given alternative management targets for nutrient reduction and alternative scenarios of climate change
14 Management Drivers Priority 3 (continued) Determine the relationship between hypoxic zone magnitude, timing, and distribution, and the distribution, production, and health of ecologically and commercially important finfish and shellfish [Gulf Hypoxia Action Plan Action 5]
15 Core System Requirements Extend spatial coverage of shelf-wide surveys Include hypoxic volume measurements on shelf-wide surveys Increase number of shelf-wide surveys Fill in temporal gaps of shelf-wide surveys with crossshelf transects Add deployments of AUVs with dissolved oxygen sensors Dissemination of relevant data and findings to management community Archival of the data in NODC
