Supplemental Information

Additional information on the details of the simulation study

Environmental Covariates

Description of environmental covariates included in the habitat models and transformations applied to normalize variables.

DOI: 10.7287/peerj.preprints.27424v1/supp-3

Description of the final MRDS models

Description of the final MRDS model used to model perception bias for each platform used in the AMAPPS surveys, species pooled in the analysis and sample size. The species pooled include humpback whales (huwh), fin whales (fiwh), minke whales (miwh), sei whales (sewh), unidentified fin-sei whale (fise), unidentified baleen whales (unbw), right whales (riwh) and sperm whales (spwh). The platform specific distance sampling (DS) model, truncation distance (W), key function (half-normal (HN) or hazard rate (HZ)), and total sample size (NTotal) for each analysis are included/shown/provided.

Data Deposition

The following information was supplied regarding data availability:

Raw data and code to run the Bayesian hierarchcial species distribution model are provided as supplementary files 3, 4 and 5. Supplementary file 3 is the code to organize the raw data and run the model in JAGS. Supplementary file 4 is the raw sightings data of fin whales formatted for entry into the model. Supplementary file 5 is the grid cell specific data for all observed grid cells including number of sightings in each grid cell and covariate values.

Funding

This study was funded in part through two inter-agency agreements with the National Marine Fisheries Service: inter-agency agreement number M14PG00005 with the US Department of the Interior, Bureau of Ocean Energy Management, Environmental Studies Program, Washington, DC and inter-agency agreement number NEC-16-011-01-FY18 with the US Navy. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.
