Description:

The North Inlet Estuary is located on the southeastern coast of the United States, approximately 10 kilometers east of Georgetown, South Carolina. The North Inlet Estuary is a bar-built Class C type estuary (Pritchard, 1955) and is a relatively small tidal estuary (area = 2630 hectares). It is composed of numerous winding tidal creeks dominated by Spartina alterniflora and is considered a pristine tidal estuary due to minimal anthropogenic impacts. The watershed drains a 24.8 square kilometer area of mostly pine forest and a moderately developed residential watershed to the north. Town Creek is a high salinity creek dominated by semi-diurnal tides. Rain input, primarily runoff, depresses salinities briefly (hours - days) depending on duration and frequency. Water temperatures mirror local air conditions: warm temperate. The DD (Debidue) site near Town Creek mouth and the Inlet is characterized by a high energy sandy bottom with regular ridges and swales. Depth along the tow path averaged 3 to 4 meters at sampling time. The bottom is sand with little or no hard substrate (shell, rock). Seasonal growths of bryozoan and algae occur. Generally, little or no organic matter is collected in the epibenthic sled. The DD epibenthos tow path site was located at the confluence of Town Creek and Debidue Creek. The 100 m tow path followed a transect beginning at a fixed point on Debidue Island and followed the shoreline due south (approximately 5 meters from shore) in line with a large, heavily-vegetated dune on North Island. The tow path terminated on a line with the boilers of a sunken ship and the tip of Debidue Island (looking to the NE). Each tow lasted approximately 5 minutes depending on tidal velocity. The BB (Bread and Butter) site is located along Town Creek approximately 2 km from the inlet mouth. At this location the creek is bounded by extensive Spartina alterniflora marshes. The intertidal zone is covered by clusters of the American oyster (Crassostrea virginica), shell rubble and intermittent muddy flats. The bottom supports seasonal growths of sponges, algae, hydroids, bryozoans, and soft corals, as well as, oysters. Much of the bottom habitat is sandy mud covered by varying accumulations of detrital plant and fecal material. Depth along the tow path ranges from 2 to 4 meters at sampling time. The BB epibenthos tow path site is located along the western shoreline of Town Creek adjacent to the mouth of Clambank Creek. Each of the tows began at a small (1 m wide) drainage creek about 50m south of Clambank Creek confluence. The tow was started about 5 m from the edge of the marsh and ended about 30 m from the edge of the marsh. The tow path extended to a line between the Clambank tower and the first small drainage southwest of Boze's Creek mouth. Each tow lasted approximately 5 minutes depending upon tidal velocity.

Methods and protocols used in the collection of this data package

Description:

Experimental Design

Since previous field studies indicated that stage of tide and time of day affected organism abundance at the epibenthic sled stations, it was necessary to make collections about every 14 days when the same tide stage occurs at the same time of day to keep these variables "constant". Thus, three sequential tows were made with the same apparatus along the same tow path when the end of the ebbing tide occurred near noon. Replicated biweekly measurements were made to allow for statistical comparisons of means among dates. Comparisons of abundance between years provided information on long term trends. Collections at a sandy inlet and a major marsh creek location allowed for a comparison of two habitat types. The same gear, field deployment, and tow paths have been used since sample no. 1.

Research Methods

Field Collection

A series of three sequential tows were made at each of 2 stations at two week intervals 2 1/2 hours prior to low tide. All collections were made during the late morning (9 - 11 am) hours. An epibenthic sled (see description) was towed behind an outboard boat motoring approximately 2 knots faster than the ebbing tidal current. All tows were made moving with the tidal flow along a marked tow path 100 m in length. Tows usually lasted approx. 5 minutes depending upon tidal velocity. Volume of water filtered was estimated with a torpedo shaped General Oceanics flow meter model 2040 mounted in the mouth of the net. Flow meter readings are recorded before and after each tow. Upon sample retrieval, the contents of the net were concentrated in the removable cod end and transferred into pre-labeled Nalgene jars and 100% buffered formalin stained with Rose Bengal added to bring the final concentration to 5 - 10% formalin. In the event of a large catch of sponge, algae, shell, or an oversized organism (greater than or equal to 1 liter volume), the sample was poured into a bucket and the excess material rinsed, noted, and discarded. The remaining sample was then sieved through a fine mesh net (less than or equal to 365 micron), placed in a pre-labeled jar, and preserved. Samples were returned to the lab for analysis.

Gear Description

Epibenthic Sled:

The apparatus consists of a rectangular steel frame (51 X 30 cm) mounted on 3 skis which orient the mouth of a #2 (365 micron) Nitex, 1/2 m mouth diameter standard conical plankton net perpendicular to the creek bottom. The apparatus does not dig into the sediment, but does collect soft-bodied sessile invertebrates (sponges, bryozoans, etc.) in addition to small motile organisms within 30 cm of the bottom. A 12m tow rope tied to the leading point of the sled chassis allowed for the best contact between the skis and the bottom along most of the tow paths.

Lab Analysis

Prior to counting, the sample is sieved, rinsed with fresh water and the used formalin disposed. The rinsed sample is then placed in a graduated beaker and sample volume recorded. In the event the volume of settled material is excessive (greater than or equal to 100 ml) the sample is divided with a cylindrical splitting apparatus until a workable fraction is obtained (never less than 12.5% of original volume). Sorting is done under a binocular dissecting microscope at 60 - 120X. All organisms of appropriate size (greater than or equal to 365 micron) are enumerated. (See Epibenthos Sample Information sheet and "Epibenthos Full Screen Management Program" for a listing of common taxa and all taxa encountered , respectively.) During the first year (1/20/81-1/9/82), 100 of each species of mysids; decapod larvae, juveniles, and adults; cumaceans; stomatopods; isopods; fish eggs, larvae, and juveniles (up to 100 per species per replicate) and rare organisms were isolated. All isolated specimens were stored by appropriate taxon in labeled flint vials and preserved in 10% formalin buffered and stained with Rose Bengal. Vials were stored by station and cruise for future analysis and reference. From 1/21/84 - 1/4/85, up to 100 of each species of fish larvae were isolated from each station. The first 100 encountered in replicates A, B, or C were in label vials and stored until length measurements were made. Larvae were measured using vernier calipers for larger specimens (> or = 10mm) or an ocular micrometer for small specimens(less or equare to 10mm). Lengths were recorded to the nearest .1mm with the ocular micrometer. Following sorting and enumeration the counted sample was recombined with the unsorted portion, placed in a labeled 500 ml flint jar, preserved with a fresh, buffered and stained 10% formalin solution and stored for future reference.

Counts

Counting sheets underwent three revisions as we become more familiar with the taxa and their relative abundance/importance over time. Copies of counting sheets used during different periods are in this documentation. The original sheet was used through cruise no. 99 the end of the first 4 years. Notes on taxonomy and life history were written on these sheets for the record. A simplified sheet with fewer categories and no entry slots for life history stages/sex was used for cruises 100-145 to speed up processing tissue. When analysis of data showed that much was lost in lumping genera and species into more general categories, and when time became available, reprocessing of those samples was done to upgrade the data base. See item 25 for details. The final counting sheet (145-present) was consistent with the IBM full screen manager. It includes sub-categories which provided resolution on the broader categories in the upper portion of the sheet. All data on the counting sheets is actual raw count data based on whatever portion of the sample was processed. Total numbers of organisms per sample were calculated using the following equations (see below), and were entered in the Motile Epibenthos Full Screen Manager. Calculating the water filtered (estimated by flow meter readings) were calculated for subsequent calculations of organism concentrations (See Equation 2).

Other Data

1) From 1/20/81 - 1/9/82, length measurements (carapace and telson) were made of the isolated adult and juvenile caridean shrimps. Data were stored by species and computer statistical analyses (length regressions, means, etc.) performed. This information is on file.

2) Four years (1/20/81 - 1/4/85) of larval and juvenile fish lengths were recorded and stored by species and year in a separate data file and screen.

3) Decapod shrimp life history and developmental staging information was recorded on data sheets, on file by cruise/date and stored in a separate computer date file. These data were entered as numbers per sample.

4) Physical information taken after zpk sampling and before epibenthos sampling have been placed into a separate data file named: fauna.physical and is merged with the epi fauna counts.

Entry verification

Multiple levels of entry verification are performed. Data were initially checked for entry errors by Beth Thomas (the data management assistant) who originally entered the data on the full-screen management entry programs. Once all data entry errors were corrected, hard copies of the data on the system were sent to Lynn Barker (the Research Specialist who counted the samples) to proof against the original raw data sheets. All data on the system from samples 1-99 have been certified error-free by Lynn Barker (date 3-28-86). Samples 100-245 were entered by Jan Blakely. Ginger Ogburn-Mathews.
