Deep Benthic Coral Habitats Of Glacier Bay National Park And Preserve, Alaska, Elise C. Hartill
Electronic Theses and Dissertations
Glacier Bay National Park and Preserve in Southeast Alaska is a system of fjords that presents an ideal natural laboratory to study terrestrial, aquatic and marine patterns of succession due to its unique and recent history of deglaciation. The patterns of deep benthic community assemblages in the fjords of Glacier Bay were investigated by quantitative assessment of underwater photo-quadrats collected using a remotely operated vehicle. The percent cover and diversity of species were lowest near the glaciated heads of the fjords and highest in the Central Channel and at the mouths of the fjords of Glacier Bay, where oceanographic conditions …

Highly Seasonal Reproduction In Desmophyllum Dianthus From The Northern Patagonian Fjords, Keri Feehan
Electronic Theses and Dissertations
The purpose of this study was to determine the basic reproductive biology and seasonality of the Patagonian fjord coral Desmophyllum dianthus. Desmophyllum dianthus is a deep-sea solitary scleractinian found throughout the world’s oceans and an important benthic habitat builder. The Chilean Patagonian fjords are the only known location where this species occurs >50 m and thus are the only place to collect samples efficiently, effectively and economically. Corals were collected via SCUBA approximately every three months (when conditions permitted) from August 2012 to September 2013 from three sites within the Northern Patagonian fjords – Lilihuape (n=76) and Punta Huinay …
