Abstract:
In freshwater bodies of New Hampshire, the most problematic aquatic invasive plant species is Myriophyllum heterophyllum or variable leaf water-milfoil. Once established, variable leaf water-milfoil forms dense beds that can alter the limnologic characteristics of a waterbody, impacting natural lacustrine communities and their habitats. Variable leaf water-milfoil infestations also disrupt recreational uses of waterbodies and have negatively affected swimming, boating, fishing, and property values in and around several lakes and ponds in New Hampshire.
In 1965, Moultonborough Bay, Lake Winnipesaukee became the first waterbody in New Hampshire where variable leaf water-milfoil was observed. Variable leaf water-milfoil is native to the Southeastern and Midwestern areas of the United States where more alkaline waters appear to limit the growth of this plant. Outside its native range, however, it adapts well to the relatively acidic, low-alkalinity, and nutrient-poor conditions of oligotrophic lakes and bays similar to Moultonborough Bay.
In 2005, the New Hampshire Department of Environmental Services (NHDES) collaborated with the U.S. Geological Survey to investigate the distribution (presence and density) of variable leaf water-milfoil in Moultonborough Bay. This study utilized geophysical systems and conventional water-quality measurements to identify lake-floor environments that may provide suitable habitat for the establishment and growth of variable leaf water-milfoil. The results of the study are intended to assist resource managers in federal and state agencies by providing methods for detecting variable leaf water-milfoil and for identifying areas susceptible to infestation. Ultimately, this information may lead to early detection, prevention, and more effective mitigation strategies.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All attributes were evaluated during data processing as standard quality control to ensure attributes contain accurate and relevant information and values.
Logical_Consistency_Report:
All sample data were collected with the mini-SEABOSS (SEABed Observation and Sampling System) by the U.S. Geological Survey in Moultonborough Bay, Lake Winnipesaukee, New Hampshire in 2005. The mini-SEABOSS is configured with a Van-Veen grab sampler to collect sediment samples of the lakefloor, and video and still cameras to collect bottom video and photographs of the lakefloor prior to collecting the physical sediment sample.
Completeness_Report:
Forty sample locations were occupied during the survey, however sediment samples were collected from only thirty-nine locations. One location (sample location 26) contained primarily large boulders and was too coarse to sample with the mini-SEABOSS. However, bottom photographs and video data were collected at this location. All forty sample locations are included in this shapefile. At sample locations 1 and 7, two sediment samples were collected for analysis due to the apparent bi-modal nature of the lakefloor and samples. At station 1, two unique sample locations were occupied in close proximity. At Station 7, one location was occupied and the sediment sample was sub-sampled. Station1A was sub-sampled in the upper 2 cm of the sample. At Station 1B, a sub-sample was collected at a depth of 2 - 10 cm. At Station 7, one sub-sample was collected from the upper 2 cm and the 2nd from the base of the sample (2 to 10 cm depth). All samples were submitted for analysis to the USGS sediment laboratory, resulting in 41 sediment samples analyzed for textural properties.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Navigation was acquired with Wide Area Augmentation System ( WAAS), which is accurate to + or - 1 to 2 meters, horizontally. Navigation data were acquired with a Communications Systems International (CSI), Inc. LGBX Pro receiver. The CSI LGBX Pro received positions from a WAAS antenna located on the port, aft roof of the R/V Rafael cabin. WAAS positions were recorded within HYPACK (www.hypack.com) navigation software. Offsets between the DGPS antenna and the mini-SEABOSS were not measured. The horizontal position of the mini-SEABOSS during sample collection is assumed to be +/- 10 meters at best, due to a lack of precise positional data at the time of sample recovery.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The depth values were collected from the hull-mounted echo-sounder on the R/V Rafael. No corrections were made to these data for draft, vessel motion, etc. Vertical accuracy is assumed to be + or - 0.5 meters.

The Mini SEABOSS was designed specifically for the USGS Woods Hole Science Center's 26-foot research vessel Rafael. This system is equipped with two video cameras, a digital still camera, and a Van Veen grab sampler. This system, weighing approximately 200 lbs., can be used to depths up to 40 meters. The grab itself is raised and lowered with a 3/16-inch Aramid fiber winch-line with a breaking strength of 5,600 pounds. The davit is secured when the Mini SEABOSS is in the water. The electrical cable is on a spring-wound take-up reel with electrical slip rings that is mounted aft of the sampler. This arrangement protects the 0.38-in. multi-conductor cable and keeps the Mini SEABOSS correctly oriented with the boat. This multi-conductor cable enables communication between the ship's lab and the Mini SEABOSS system. The digital camera, a Minolta Dimage 7Hi, is mounted in a machined Delrin housing with a flat port and is set for 2560 x 1920 pixel images at the "fine" setting for compression. This allows the camera to be used for over 200 images with a 1 GB Compact Flash card without downloading. The system also has a 50 Watt/second flash unit powered by 8 AA batteries. Two battery-powered lasers are set 15 cm apart for scale measurements. The red laser dots can usually be seen in the photo depending on the bottom type and the distance to the sea floor. A third battery powered laser is positioned at an angle so that when it intersects the other lasers, the Mini SEABOSS is at the optimum height off the bottom for a still photograph (optimal height is generally 75 cm above the bottom). The camera is set to a manual focus and set to a default focus distance (50 cm) once the camera is powered up. The default focus distance is slightly less than the optimum height above the seafloor to account for optical distortion under water.
Video images were collected at 40 sample locations and digital photographs were collected at 36 of the 40 sample locations using the USGS Mini SEABOSS (Blackwood and Parolski, 2001). The sample locations were selected based on variation in the acoustic backscatter within the sidescan-sonar mosaic, with the objective of characterizing broad areas of different backscatter intensity. With the Mini SEABOSS deployed, the research vessel was allowed to drift with occasional power from the vessel to control drift direction. Video was collected over a total of 696 meters of lakefloor. Video drift position was derived from the HYPACK navigation files based on the start and end times of the drift. For some portions of the drift, there was no navigation, so the position was derived from the time and position in the video at 30-s intervals. Latitude and Longitude for sample locations 1 and 8 were derived solely from the video as HYPACK files were not saved to disk at these sample locations. Bottom photographs were generally taken immediately prior to collecting a sediment sample with the SEABOSS. A unique navigation position was not recorded when the bottom photographs were collected, however the time of photo collection was recorded.
Grab samples of the surficial sediment were collected at 39 of the 40 sample locations, typically at the end of a drift. Sample location 26 was not sampled, as the sediment was too coarse to successfully sample (boulders). However, bottom photographs and video were collected. The upper 2 cm of sediment was scraped from the surface of sediment samples for texture analysis. At sample locations 1 and 7, two sub-samples were collected due to the apparent bi-modal nature of the lakefloor and sample. One sub-sample was collected from the upper 2 cm, and the 2nd sub-sample was collected from the base of the sample (2 to 10 cm depth). (Two individual sites were occupied at Station 1, whereas only one site was occupied at Station 7. The one sample collected at Station 7 was subsequently sub-sampled).
A total of 41 bottom samples were submitted for grain-size analysis. Grain-size analysis was performed at the USGS Sediment Laboratory at WHCMSC using methods described by Poppe and others (2005).
Note: A small bit of water entered the camera housing during survey operations. This is reflected as a blurred 'dot' on the bottom photographs. The camera remained operational and data collection continued despite the 'water mark'.

Grab samples were collected with the mini SEABOSS (Blackwood and Parolski, 2001) at thirty-nine sample locations in Moultonborough Bay, Lake Winnipesaukee, New Hampshire, 2005. Forty sample locations were occupied, but one location was too coarse to sample.
The upper 2 cm of sediment was scraped from the surface of the sample for texture analysis. At sample locations 1 and 7, two sub-samples were collected due to the apparent bi-modal nature of the lakefloor and sample. One sub-sample was collected from the upper 2 cm, and the 2nd sub-sample was collected from the base of the sample (2 to 10 cm depth). (Two locations (sample sites) were occupied at Station 1, and one location (sample site) was occupied at Station 7).
Forty-one samples in total were submitted for grain-size analysis to the USGS Sediment Laboratory at the Woods Hole Coastal and Marine Science Center using methods described by Poppe and others (2005).
This and all subsequent processing steps were conducted by Jane F. Denny.
