Examination of species-environment relationships that determine broad-scale distribution patterns is a key focus of ecological research. Characterizing animal-habitat associations in the marine environment is particularly challenging given the opacity of the ocean, and addressing this question in marine systems has consequently lagged behind terrestrial systems. In this project, we have leveraged existing data on locations of a large marine predator, the Sixgill Shark, Hexanchus griseus, and linked that with the PNNL’s Salish Sea Model over the domain of shark movement in Puget Sound, Washington state.

This is an attempt to orient you around R, to give you a roadmap of sorts, to help you find your way when learning R. The following text will show you: What R is What R studio is How to do basic math in R How to add data and read basic R syntax How to make a linear model and a basic plot How to add packages What a dplyr pipe is How to plot with ggplot This is, of course, just the tip of the iceberg as far as R goes but hopefully this orients you so that you can follow along in future R sessions.



Classification of Ocean Communities

The boundaries and forces structuring the marine environment are in many ways distinct from terrestrial systems. This classification builds off terrestrial classifying efforts but adapts it to ocean biomes to develop a scheme which effectively sorts marine biomes.

Data Representation of Acoustic Telemetry

Passive acoustic telemetry is a commonly used method of investigating marine fish behavior. My work examines the interaction between behavior and sampling to allow researchers using passive acoustics as a tool to ask more intricate and sophisticated ecological questions.

Habitat Use by Sixgill Sharks

Sixgill Sharks are a deep water shark with a worldwide species distribution. In Puget Sound their presence is known, but the particular variables they are responding to is less understood. We have developed a method of creating a habitat suitability model for this species by combining acoustic telemetry data with the Pacific Northwest Laboratories Salish Sea model.
