We report on two sightings of individual blue whales (Balaenoptera musculus) off the coast of Virginia during marine mammal surveys. On 11 April 2018, during a vessel survey off the coast of Virginia, a single blue whale was observed approximately 100 km east-northeast of Virginia Beach. On 10 February 2019, another single blue whale was recorded during an aerial survey approximately 135 km east-southeast of Virginia Beach

Aerial Surveys of Marine Mammals Conducted in the Inland Puget Sound Waters of Washington, summer 2013 – winter 2016
Project Objectives
1) Conduct aerial surveys during four seasonal periods within the inland Puget Sound Survey Area to assess potential differences in seasonal distribution, numbers, and behavioral state patterns of marine mammals; 2) Collect data to estimate densities of marine mammals in the inland Puget Sound waters for species with sufficient sightings; 3) Estimate abundance for each marine mammal species seen an adequate number of times; 4) Document the distribution and habitat use of each species observed; 5) Document and describe behaviors seen without performing focal follows.

Vessel-based Marine Mammal Surveys in Puget Sound, Washington
Project Objectives
Conduct marine mammal in-water vessel-based line transect surveys in the Puget Sound basin to: 1) Record data on all marine mammal species seen with the study area, with a focus on the killer whale (Orcinus orca) and the harbor porpoise (Phocoena phocoena). 2) Identify the seasonal occurrence and abundance/density of cetaceans within the study area. 3) Identify the effects of environmental variables on the distribution and abundance of species in the study area.No related blog posts to display
