Prince William Sound Regional Citizens Advisory Council
Marine Invasive Species Monitoring 2009 - 2014

Objectives: Monitor Chenega Bay area for non-indigenous species, particularly for the European Green Crab (Carcinus meanus). Chenega Bay is only one of a network of sites established by PWSRCAC to detect the arrival and spread of green crabs in Alaskan waters.

Methodology: Monitoring traps are deployed for 24 hours during minus tide events throughout the summer. Traps are collected, species caught identified and recorded. Tunicate monitoring was added to this project's scope in 2011.  Ten settlement plates are deployed at the Chenega Bay Small Boat harbor.  These plates are switched out once a year and data recorded for types and amounts of marine invertebrates.  Invasive tunicate species have been found in Prince William Sound waters. No green crabs have been currently found.

Chenega Bay Hummingbird Banding Project
Ongoing project since 2007

Objectives:  Under the supervision of Master Bander Stacy J. Peterson (USFWS Permit # 23148) rufous hummingbirds (Selasphorous rufus) are captured, marked and released in order to determine relative abundance and population dynamics.  Our project operates the only season-long hummingbird banding station in southcentral Alaska, and the most northern in the world. The CBHBP is currently in the process of obtaining a Federal non-profit 501 c 3 status to continue, and expand, hummingbird research, conservation and education in Alaska.  Look for more information on the developing Alaska Hummingbird Project in 2015.

Methodology:  Rufus hummingbirds are banded with U.S. Fish and Wildlife Service unique identification bands, weighed and morphological data recorded, and then released unharmed.   See the Publications page for more information on this project which is gathering ground breaking migration and life history data on rufous hummingbirds. 



National Oceanic and Atmospheric Administration
Humpback whale (Megaptera novaengliae) project

October 2006 - March 2010

Objectives From 4 select bays near Chenega Bay, Alaska, estimate the abundance and residency of winter humpback whale populations and identify humpback whale prey.

Methodology:  SPLASH network protocols for humpback whale observations, individual identification with digital camera photos and physical data collection. Authorized under the National Marine Mammal Laboratory's cetacean permit #782-1719.



National Oceanic and Atmospheric Administration
Pacific Herring (Clupea pallasii) project

October 2006 - April 2008

Objectives: Sample multiple age classes from the vicinity of Chenega Bay, Alaska. 

Methodology:  Field work entails collecting herring with the use of hook & line and photo documentation of predation on herring by marine mammals, sea birds, and sharks.  Samples are frozen and shipped to NOAA Fisheries Auke Bay Lab.
