Marine Derived Nutrients Quarterly Tasks

2004 Quarterly Project Tasks:

1st Quarter Tasks (October 1, 2003 - December 31, 2003)
Status: Complete

Tasks to be performed:

November 10, 2003: EVOS TC approval and notification

Progress report:

Update from Project Manager: First Quarter objectives have been met.

2nd Quarter Tasks (January 1, 2004 - March 31, 2004)
Status: Complete

Tasks to be performed:

January - February 2004 Workshop in Homer to discuss year one of the study, include states biologists, federal biologists, volunteer citizen monitors, native Alaskans and researchers. March 2004 Coordinate/communicate with other proposed MDN research in Kenai River and Prince William Sound. Prepare for sampling.

Progress report:

Update from Project Manager: Second Quarter objective have been addressed. Rather than a single workshop, the PI's chose to discuss the project through several venues because the logistics and cost of coordinating travel for a single workshop were too great. November 2003: held a conference call that included local and regional state fishery biologists, citizen monitoring groups, and federal fisheries biologist to discuss the proposed study plan. January 2004: Mark Wiplfi and Coowe Walker attended the EVOS workshop in Anchorage and held a meeting during the conference with ADFG biologists, biometricians and KBRR researchers. February-March 2004: Coowe Walker met with local fisheries biologists on several occasions to discuss and coordinate operation of the weir and the sample design. PI's have initiated communication/coordination with other MDN projects. Preparations for sampling are well underway.

3rd Quarter Tasks (April 1, 2004 - June 30, 2004)
Status: Complete

Tasks to be performed:

April - June 2004 Sampling on treatment and control watersheds Annual Report preparation.

Progress report:

Update from Project Manager: Third Quarter objectives have been met. The weir on the North Fork of the Anchor River was installed between May 3-16 with assistance from the ADFG Division of Sport Fish. Final sample station site selection on the North Fork of the Anchor River and on Happy Valley Creek occurred in early May. Five stations on both the North Fork and on Happy Valley Creek were selected as sample sites. Monthly water chemistry and stream discharge sampling began in May. At the advice of the Reserve's oceanographer, the nearshore sampling was modified to sample to the south of the mouth of each stream because the freshwater plumes from the streams extend a great distance into the Inlet, but are quickly diverted towards the north by the Alaska Coastal Current. All of the food web samples have been dried and homogenized. PI's were unable to find young-of-the-year fry for the Heintz growth allocation study. In lieu of this, it was decided that slightly larger juvenile Dolly Varden and slimy sculpin could be used. Samples were collected from the five upper sampling stations on each stream in May and in June. Due to the large amount of community interest in this project, we decided to develop a quarterly newsletter to distribute to people in the community.

4th Quarter Tasks (July 1, 2004 - September 30, 2004)
Status: Complete

Tasks to be performed:

July - September 2004 Sampling on treatment and control watersheds Annual Report preparation.

Progress report:

Update from Project Manager: Fourth Quarter objectives were met as follows: The weir on the North Fork of the Anchor River was removed on September 15 with assistance from the ADFG Division of Sport Fish. The weir enabled us to sample the chinook and coho runs on the North Fork of the Anchor River. In August, we completed the second round of food web sampling, intended to assess the marine derived nutrient inputs from the chinook run. Food web samples have been prepped for stable isotope and fatty acid analysis. Weekly water chemistry sampling at the weir site (station 5 on the North Fork) and on station 5 of Happy Valley Creek continued until September 15, when the weir was dismantled. The samples have been submitted to the Cook Inlet Keeper for analysis. We expect to receive data from the Keeper at the end of November. We continued to collect algal growth samples every three weeks in order to analyze chlorophyll production and biomass. Our efforts to capture data from nearshore moorings with larval/algae collection plates failed when the moorings were lost at sea. We collected juvenile Dolly Varden from the five upper sampling stations on each stream in August. We arranged with Ron Heintz, who is analyzing these fish for growth allocation, that the same fish could be used for fatty acid analysis, thereby reducing the number of fish for growth allocation, that the same fish could be used for fatty acid analysis, thereby reducing the number of fish that we need to sacrifice. In addition to the juvenile fish, we collected 5 adult female chinook with eggs from the weir and sent these frozen to the Auke Bay lab. Annual report submitted and on the web.
