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.
Field activity information for this cruise is available on-line through the U.S. Geological Survey Coastal and Marine Geoscience Data System https://cmgds.marine.usgs.gov/fan_info.php?fa=2005-004-FA.
This shapefile includes the trackline navigation for video data collected at 40 sample locations within Moultonborough Bay, Lake Winnipesaukee, New Hampshire during USGS field activity 2005-004-FA. The video data were collected in order to ground-truth geophysical data and characterize the surficial sediment distribution of the lakefloor. The video trackline navigation shows the coverage and locations of the video data collected within the survey area and can be used to correlate the video data with sidescan-sonar, subbottom and bathymetric data for analysis.

All attributes were evaluated during data processing as standard quality control to ensure attributes contain accurate and relevant information and values.
All bottom video data were collected in 2005 with the mini-SEABOSS (SEABed Observation and Sampling System, Blackwood and Parolski, 2001) by the U.S. Geological Survey in Moultonborough Bay, Lake Winnipesaukee, New Hampshire.
Video data were collected at 40 sample locations using the USGS Mini SEABOSS (Blackwood and Parolski, 2001).
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.

Video images were collected at 40 sample locations and digital photographs were collected at 35 of the 40 sample locations using the USGS Mini SEABOSS (Blackwood and Parolski, 2001). Mini SEABOSS stations were selected based on preliminary acoustic-backscatter mosaics, 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. Continuous 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 stamp in the video at 1-minute intervals. Latitude and Longitude for sample locations 1 and 8 were derived solely from the video as HYPACK was not recording.
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 drift positions were extracted from HYPACK navigation files based on the start and end times of the drift and saved as a comma-separated value (*csv) file.
During sample locations (i.e. drifts) 1 and 8 HYPACK navigation were not recorded, so the latitude and longitude at 1 minute intervals were read directly from the video data and added to the *csv file.
This and all subsequent processing steps were conducted by Jane F. Denny.

The *csv file was imported to ArcGIS 9.0 using Tools- Add XY data. An event theme was created. The event theme was saved as a shapefile and the projection was defined as Geographic Coordinate System, WGS 84.
The point shapefile was used as an input for Points to line in VACExtras (version 1.8), a VB collection of tools developed by VeeAnn Cross (USGS-WHCMSC), which converts point data to a new polyline shapefile, based on the order of records in the table with a unique identifier used to group the points into a line. In this instance, that unique field was STATION.
A 'length' field was added to the attribute table using XTOOLS 6.2.0. Length is stored in meters, UTM Zone 19N projection.
Fields, Cruise_ID, Jday, Acq_Date and System were added to the table by adding and populating fields within ArcGIS 9.0.
2005
ArcGIS 9.3, Xtools 7.1.0 (Build 738) was used to convert polyines to points using Xtools, Feature Conversion, Convert Features to Points, generating a new shapefile. Xtools was then used to add X,Y coordinates to the new shapefile table, using Xtools, Table Operations, Add X,Y,Z coordinates. The table was then exported to a text file using, Xtools, Table Operations, Export table to txt. The txt file was saved as a *.csv. The *csv can then be used outside of the ArcGIS 9.3 environment to generate trackline data, if neeed.

The online links to the data were updated to reflect the new server hosting the data. Additionally, other small edits could be made to the metadata, such as modifying http to https where appropriate. The metadata date (but not the metadata creator) was edited to reflect the date of these changes.
