The Virginia Coast Reserve LTER
1996-1997 Annual Report
1 August 1997
VCR LTER Highlights
UNDERGRAUDATES AND LTER RESEARCH -- We have buildt a new database and data and information delivery system for site biodiversity data. This project was a joint effort between VCR LTER PIs and undergraduate students at the University of Virginia. The biodiversity data base was designed in the Fall of 1996 by a team of 6 students and three PIs. The system was programmed and filled with data on all taxa in the spring of 1997. 33 undergraduate students were involved in the filling of this system from published data. Nearly 6000 species observations were put in the system by the students. This data base and the system display of data for the user are ON-LINE.
NEW THEORETICAL CONSTRUCT OF MARSH AND LAGOON SYSTEMS -- A new morphometric analysis of coastal watersheds and lagoons provides a detailed understanding of the extent and complexity of coastal marshes. The model has special application for the prediction of changes in estuarine marshes resulting from sea level change.
1969 ATLANTIC COAST WIDE EROSION REVERSAL -- Shoreline change rates at the VCR reversed their direction of change (erosion and accretion) in 1969. We have established that this reversal of pattern of coastal erosion applies to the Atlantic Coast from Florida to Cape Cod. This past year we identified a similar reversal in the boundary between the beach and inland vegetation (an ecotone) followed, in time, the change in shoreline erosion. These changes are due to changes in storm climates.
Other Important findings at the VCR LTER
HEDGE ROWS AND GROUNDWATER NUTRIENT FLUXES -- Control on agricultural nutrients flows into tidal creeks by means of groundwater pathways. We established even a narrow hedgerow of trees was sufficient to shut-down this pathway of nutrients in to tidal creeks.
FRANKIA DISPERSAL PRECEDES SHRUB INVASION -- The nitrogen fixer Frankia (on roots of the coastal shrug Myrica) disperses in fresh new sand deposits within 5 years. Shrub colonization is this not limited by a lack of the bacterium and may account for the extreme rapidity of expansion of coastal shrublands.
IN SITU MICROBIAL COMMUNITY CLASSIFICATION -- Naturally occurring microbial communities can be classified on the basis of metabolic use patterns of 100 standard carbon sources. The classes found are stable from place to place and from season to season.
LEGACY SUPPORTS NEW MARSHES -- The rate and course of salt marsh initiation and development are a function of the subsurface flow of fresh ground water from adjacent uplands. We have also established that incipient marshes built on beach sands that use nitrate as a nitrogen source lag by two decades over marshes established on buried mudflats that use ammonia as a nitrogen source. This will aid in understanding the progress of wetland restoration in coastal areas.
HYPERSALINE PLUME UNDER ISLANDS -- Hypersaline (140 ppt) pore water on VCR barrier island salt flats sinks as a plume into the island sands to a depth of at least 9 meters. The fate of these high saline solutions are not yet established.
Ecosystems, Storms and Sealevel
SEDIMENTATION AND SEALEVEL RISE -- Marsh sedimentation, essential for marsh growth upward to keep up with sealevel rise, only occurs during a 2 hour window at high tide (>1 m) when there is a wind tide from the Northeast. As coastal storm produces such wind tides. Marsh upward growth is subject to long term trends in storm climate. In addition, we established that the stems of marsh plants lower to tidal flow velocities below 1 cm/s and permit deposition if other conditions are present.
COASTAL STORM CLIMATE CHANGE -- Coastal storm in the VCR region reached a low frequency in the first decade of this century and a high frequency in the 1960s. The amplitude of this change is 2-fold in number. This climate change drives coastal erosion patterns and apparently the health and vigor of marshes at the VCR.
STORMS AND PREDATION -- High storm flooding frequency and increased avian and mammalian predation of colonial gull-billed terns has reduced per nesting survivorship to fewer than one bird per nest. This is below the population replacement. While based on the 1994-1997 period, population structure changes could result from a continuation of this circumstance.
KEEPING UP WITH SEALEVEL -- Experiments at the VCR indicate that increased flooding (as in sealevel rise) and storm deposited wrack both have the effect of reducing respiration and thus decomposition. These adjustments may contribute to the organic matter accumulation in marshes and the capacity to keep up with sealevel rise.
NEW SOFTWARE --Software designed for creation of annual LTER research reports using a WWW-form has had much wider use than originally anticipated. The software makes it possible to rapidly create an automated system for receiving and displaying information over the WWW. Data from the WWW form is pasted into a template document to create a new WWW page. An automatic table of contents for submitted entries is then generated. This VCR software was also used to obtain community input on LTER/LMER consolidation, develop the LTER Network Regionalization document and even for processing of abstracts for the ERS/SEERS meeting.
NEW VCR-WWW SYSTEM SOFTWARE -- The VCR/LTER Information Management System was moved to a WWW interface. Although the system has used the WWW for display and access since it came online in 1993, input to the system was via database software that was not WWW accessible. The new system allows investigators at seven institutions in four states to directly input and edit information about new datasets and to update information on older datasets without intervention by the site information manager. Changes in the database immediately show up in queries by data users. The system uses a forms-based interface to a SQL relational database (Mini-SQL). The data model for the system is hierarchical. PROJECTS may have one or more DATASETS each of which has one or more VARIABLES which may have zero or more CODES. The database has links to an existing personnel database, so an that investigator's address information is automatically updated. The system has been enthusiastically received by investigators and graduate students. Additional training on using the system is planned for the fall of 1997.
Activities in the next funding year (1997-1998).
In 1997-1998 we will install 30 sediment platforms at the VCR in conjunction with a world-wide effort to measure sediment deposition in marshes. With this measurement system we will be able to directly record from year-to-year and over decades the rate of rise of marsh elevations. Indirect evidence indicates a loss of marsh of 11% since 1850. However we do not know the shortfall in marsh rise that results in such marsh-area loss.
With the acquisition of a GPS-coordinated, digital fathometer new bathymetric surveys of Hog Island Bay will be initiated next spring. From these analyses we will, for the first time, be able to estimate tidal volumes and test a new hypsometric theory (Oertel) at several of our marsh study sites.
With our new motion-stabilized digital video camera will map bottom attached macroalgae in our lagoons and establish a series of permanent plots to record macroalgal standing stock. It is common lore in the region that the lagoon bottoms of the VCR are seeing a increase in attached macroalgae. As such changes might give rise to increases and water clarity, it is essential that we measure these changes.
The VCR LTER is buildimg new Field Station at Oyster, VA. A grant from the University of Virginia (450K) and from a graduate of the University of Virginia ($1M) are being used to purchase and construct phase one of a new field station for research. PIs of the VCR LTER have worked over the last 3 years to reach this point and we expect construction to begin in the Fall of 1997.
We expect to link our biodiversity database with the Man and Biosphere initiative and data share. The VCR is a Man and the Biosphere site and we have begun talks to accomplish a data link.
Information about Data Management
Progress an d New Developments
1. We have developed WWW based tools for field data entry directly into our electronic data bases. Once the PI has established the metadata fields, the process from data input to dynamically generated webpages of data will be automatic to ON-LINE status.
2. We have built a new database and data and information delivery system for site biodiversity data. This project was a joint effort between VCR LTER PIs and undergraduate students at the University of Virginia. The biodiversity data base was designed in the Fall of 1996 by a team of 6 students and three PIs. The system was programmed and filled with data on all taxa in the spring of 1997. 33 undergraduate students were involved in the filling of this system from published data. Nearly 6000 species observations were put in the system by the students. This data base and the system display of data for the user are ON-LINE.
