Primnoa pacifica Reproduction in Shallow Versus Deep Habitats of Glacier Bay National Park and Preserve, Alaska
Primnoa pacifica is a species of deep-sea cold-water coral that can be found in Glacier Bay National Park and Preserve in Alaska. These colonies are important to their ecosystem as they provide habitat for other species living in this area. One thing that makes P. pacifica important to study is that...

The colony samples were collected from White Thunder Ridge in Glacier Bay National Park and Preserve on March 20th, 2016. Using histology methods from Waller et al.

Primnoa pacifica is a species of deep-sea cold-water coral that can be found in Glacier Bay National Park and Preserve in Alaska. These colonies are important to their ecosystem as they provide habitat for other species living in this area. One thing that makes P. pacifica important to study is that the species displays deep-water emergence. This is a phenomenon where species normally found in deep waters can exist in shallower waters, allowing easier access for research. The purpose of this thesis was to determine if depth effects the reproduction of male P. pacifica colonies. Two colonies from deep depths (167m and 178m) and two colonies from shallow depths (15.54m and 19.2m) were examined.
