Title: Seafloor photographs and location data, West Hawaii, 2010-2011
Abstract:
Seafloor photographs were collected by SCUBA divers along pre-determined transects using an underwater digital camera following benthic survey protocols developed by the National Park Service (NPS) at Kaloko-Honokohau National Historical Park (Marrack and others, 2014; Weijerman and others, 2014) and modeled after the U.S. Geological Survey (USGS) and NPS coral reef survey protocols (Rogers and others, 2001; Brown and others, 2011). This dataset includes seafloor photographs in jpg format, the locations of which are described in the accompanying comma-separated files.

Why was the data set created?

As part of an integrated study to assess projected impacts of land-use and climate change on nearshore habitat conditions and coral health, the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center (PCMSC) initiated an investigation of nearshore water properties, coral health indicators, and circulation modeling along the west Hawaii Island coast.

How was the data set created?

  2. How were the data generated, processed, and modified?
    Date: 09-Nov-2011 (process 1 of 3)
    Seafloor photographs were collected in June and October 2010 and in October/November 2011 by divers on SCUBA along three randomly selected transects at each site location. The location where divers descended at the beginning of each transect was noted using a portable GPS unit in a waterproof housing. Once at the seafloor, a bearing was noted for the direction the divers swam and distance from start to each station noted along a 10-m measuring tape. Each transect was photographed using an underwater digital camera a 0.6 m above the seafloor. Photographs were taken on both sides of the transect tape at 0.5 m intervals. Photographs from the right side of transects were analyzed with CPCe except in cases where photo clarity or completeness was best on the left side of transect.
