How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I'm involved in many various projects and have the flexibility to pursure many fields of study. Currently my work centers on: - GIS analysis of coastal habitat change - SLR and urban development impacts to bird species - Understanding the spatial and behavioral scope of marine debris in the Upper Texas Coast - Monitoring of endangered coastal waterbirds and shorebirds

Technical Report

Intertidal oyster reefs are an important habitat type within the estuarine landscape and provide many unique ecosystem services. Within West Galveston Bay, Texas, this habitat type is relatively understudied, and the spatial extent has not been recently quantified. Along with the quantity of intertidal reef habitat, information on the present compo...

Green Island, located in the Lower Laguna Madre is a major nesting site for Reddish Egret and was named a Priority Reddish Egret Nesting Colony site by the Gulf Coast Joint Venture in 2009. The National Audubon Society (NAS) has leased Green Island from the State of Texas since 1923 and manages the island as a sanctuary for colonial waterbirds. Sin...

Account caught on field camera of predation event involving an unknown snake species eating American Oystercatcher eggs.Due to the poor quality of the images, we were unable to precisely identify the snake to species. However, based on its size, movement, and coloration, we postulated that it was either an Eastern Ratsnake or North American Racer.
Conference Paper
Overview of current waterbird trends in Galveston Bay using Texas Colonial Waterbird Society data form annual surveys. Emphasis on brown pelican and laughing gull population increases.

Barrier islands and coastal beach systems provide nesting habitat for marine and estuarine turtles. Densely settled coastal areas may subsidize nest predators. Our pur-pose was to inform conservation by providing a greater understanding of habitat-based risk factors for nest predation, for an estuarine turtle. We expected that habitat conditions at...

Reptiles are experiencing global declines and pond turtles (Emydidae) are particularly vulnerable. The diamondback terrapin uses multiple habitats to fulfill its life history requirements, in the estuarine environments of the Gulf Coast and Atlantic states (US). Interacting effects of coastal development, overharvesting, abandoned crabbing gear, ro...


Question (1)
I've used the DSAS extension by USGS successfully before, but this is the first time on a new computer.  I'm running Windows 10, Arc version 10.4.1.  I've been banging my head against the wall for two days on this.  The DSAS website is down and google searches are getting me nowhere.  I'm hoping one of you has come upon this issue before.
I've gotten the error every time I run the statistical calculations on transects.  My data seems fine, I even downloaded the sample dataset to make sure it wasn't an issue with my files.
So far I have:
-Turned off background geoprocessing
-Modified/ simplified/ double checked file names
-Uninstalled and reinstalled both my ESRI programs and DSAS
-Tried to run the analysis with different data
-Checked and rechecked the required programs/ installations for DSAS
-Restarted ArcMap, double checked projections, etc.
-Made sure I never had the ArcCatalog or Search windows open- DSAS can be a quirky little monster on things like that
Any suggestions would be very helpful!  This is the most current version of ArcMap and I'm wondering if there is an issue with the new version. There are no issues with memory usage or the data being too large- the CPU is fine and the dataset is smaller than ones I've run before.
Here is the error message from my output log:
[9/13/2016 12:41:18 PM] : Exception Message:
