Productivity and resilience: long-term trends, seasonal variability, and event-driven changes to the plant community of the accreting Wax Lake Delta

Date: Thursday, April 17, 2014 at 12:00pm EDT

Speaker: Melissa Carle

Abstract: River deltas are dynamic depositional environments that are controlled to varying degrees by coastal and fluvial forces. Plant communities in deltas respond to many of the same allogenic forces that shape delta geomorphology. This study examines long-term trends, seasonal variability, and storm and flood event-driven changes in the plant community of the Wax Lake delta, a young, actively accreting river delta in coastal Louisiana, USA. A vegetation index (NDVI) calculated from a time series of 94 Landsat MSS and TM images was used to assess the long-term trends, seasonal fluctuations, and storm-event driven changes in plant community productivity within the delta. Analysis of peak growing season NDVI from 1975 to 2011 indicates that both total and mean (per unit area) NDVI in the delta have increased over time and that seasonal fluctuations occur that are related to water temperature and discharge. Comparison of NDVI data from before and after major storm events shows that storms passing directly over or to the west of the delta have a significant short-term impact on the plant community, most likely as a result of salt-water intrusion associated with storm surges. However, in each case, NDVI values recovered to within the 95 percent prediction interval for the long-term trend by the following growing season. Additionally, a combination of WorldView-2 and Land Satellite 5 Thematic Mapper imagery was used to assess the impact of the 2011 Mississippi River flood on the Wax Lake Delta. Vegetation community change was mapped from 2010 to 2011 and related to elevation change using plant species elevation distributions calculated from light detection and ranging (LIDAR) data. Changes in the land area in the delta were also assessed by regressing land area against water level for a series of pre- and post-flood Landsat 5 TM images. The results indicate a net growth of the areal footprint of the delta of approximately 5 km2 at mean sea level following this important flood event. Areal gains were greatest at high water levels, indicating substantial vertical accretion occurred across the subaerial delta. In addition, conversion from lower to higher elevation species was observed over at least 8.7 km2, or 31.8%, of the area studied. Overall, these results indicate that the plant community in the Wax Lake delta is increasing in productivity as the delta matures and continues to accrete both vertically and horizontally over time. The marshes in the delta show great resilience to storm disturbance, and a strong response to allogenic succession driven by extreme flood events. As the Wax Lake delta is essentially the product of an unmanaged river diversion, its productivity and resilience have important implications for large-scale diversions that have proposed to restore marshes elsewhere in the Mississippi River deltaic plain.

Information Resources for all NOAA staff: LexisNexis

Date: Wednesday, May 14, 2014 at 12:00pm EDT

Speaker: Mary Lou Cumberpatch, NOAA Central Library, and Chris Vestal, LexisNexis

Abstract: The NOAA Central Library, in cooperation with the Department of Commerce, provides access to the LexisNexis information service for all NOAA federal and contract staff. LexisNexis provides you with access to hundreds of full-text news and journal sources, including the Washington Post, New York Times, Harvard Business Review, The Atlantic, PC Magazine, and Popular Science. The service allows you to track legislation, find Congressional documents, cases, treaties, law reviews and more. This webinar will give you the tools to locate relevant sources for your work.

Searching for Accountability: Do Efforts Such as GPRA, GPRAMA, and PART Help?

Date: Thursday, June 26, 2014 at 12:00pm EDT

Speaker: Beryl Radin, Georgetown University, McCourt School of Public Policy

Abstract: For the past several decades, performance measurement requirements have become a crucial part of the effort to improve accountability in the federal government. Requirements have been attached to the budget process that seek to link measures of effectiveness to the funding of those programs. While the urge to improve program effectiveness is commendable, the experience with GPRA and PART has not always led to that goal. This presentation will review the reasons for this problem and draw on the NOAA experience with these efforts

Note: This seminar is sponsored by the NOAA Evaluation Committee.
