Science Night 2023 – Videos now available

Systems and Methods: Connecting across the Exxon Valdez oil spill region

Science Night is an annual event hosted by the Prince William Regional Citizens Advisory Council. Topics focus on research related to the safe transportation of oil through Prince William Sound.

Individual presentations can be viewed below, or you can view the full playlist directly on the Council’s Youtube Channel: Science Night 2023

Let the Hydrocarbons in Prince William Sound Talk: 30 years of Environmental Monitoring through PWSRCAC’s LTEMP

Presenter: Dr. Morgan Bender, Senior Scientist, Owl Ridge Natural Resource Consultants, Inc.

The PWSRCAC’s Long-Term Environmental Monitoring Program (LTEMP) is one of the longest-standing hydrocarbon assessment programs of its kind and provides us with annual data on how and where hydrocarbons enter Prince William Sound and the potential effects they may have on the marine ecosystem. Morgan, an Alaska-based ecotoxicologist, will lead us through the 30-year LTEMP investigative process and major findings to inform and excite Science Night participants on LTEMP’s past, present, and future.

Forage Fish Update

Presenter: Scott Pegau, Research Program Manager, Oil Spill Recovery Institute

Forage fish provide a critical link between plankton and large predators like birds, mammals, and other fish. Pacific herring, sand lance, capelin, and juvenile pollock are a few of the many forage fish in PWS. Most of the information we have on forage fish is associated with herring because of its historic commercial importance but there is some information on other species. This presentation takes a look at some of the existing research into forage fish in Prince William Sound.

Advancing our understanding of tsunamigenic landslide hazards in Prince William Sound, Alaska

Presenter: Dennis M. Staley, Research Physical Scientist, U.S. Geological Survey – Alaska Volcano Observatory

Exposure to landslide and tsunami hazards are a part of life for those who reside in the seaside communities of coastal Alaska and the people who work or recreate in coastal waterways. Recently, the recognition of the landslide-generated tsunami hazard posed by the Barry Arm landslide in northwestern Prince William Sound has attracted considerable attention in the public and media, at local, state, and federal governments, and in the scientific community. This presentation focuses on the ongoing effort to assess hazard and warn for a tsunami produced by the Barry Arm landslide, and on scientific investigations into the prevalence of this type of natural hazard at other locations in Prince William Sound.

Alaska Spill Response Wildlife Aid

Presenter: Bridget Crokus, Deputy Oil Spill Response Coordinator, USFWS Alaska Region

Protecting fish, wildlife, and their habitats is a primary response objective after an oil spill. First-hand accounts of wildlife in or near an oil spill are invaluable to a successful wildlife response. Bridget will present the Alaska Spill Response Wildlife ID Aid, a tool developed to help spill responders “take a wildlife minute” and record the wildlife they see.

Clicking on the image will download a PDF of the report.The Council’s annual report, Year in Review 2022/2023, is now available. This report covers the many programs and projects we’ve been working on over the past year, such as oil spill prevention and response, environmental monitoring, oil spill contingency plans, operations at the Valdez Marine Terminal, invasive species monitoring, our outreach efforts, and much more. Highlights from this year include:

  • An assessment of risks and safety culture at the Valdez Marine Terminal
  • Ensuring the adequacy of secondary containment liners for the terminal’s crude oil storage tanks
  • Supporting solutions for sustainable funding for state spill
    prevention and response
  • Improvements to how the Council monitors weather and sea currents in our region
  • Monitoring oil spill drills and exercises
  • Reexamining the Council’s position on use of dispersants in our region

New station at Copper River Delta to monitor for high winds

The Council recently sponsored a new addition to the weather station network. The new station was placed near the mouth of the Copper River Delta on a small island known as Kokinhenik Bar.

The Copper River Valley can funnel high winds when there is a high-pressure system over interior Alaska and a low-pressure system over the Gulf of Alaska. Oil-laden tankers travel shipping lanes a little over 23 miles away, so this information will aid in the safe transportation of oil, and an important asset in the event of a spill.

A link to the data from this weather station, along with other weather tracking resources is available on our website: Tracking Weather for the Safe Transportation of Oil

Analysis of weather conditions released

A new report summarizes weather data collected in Port Valdez. Two buoys, one near the Valdez Marine Terminal and another near an environmentally sensitive area called the Valdez Duck Flats have been collecting information since 2019.

Dr. Rob Campbell, researcher at the Prince William Sound Science Center, has been analyzing the data and just published a report on his analysis of the first three years of data. He is looking at ocean currents, wind direction and speed, wave direction and heights, and other information for possible trends between years and seasons.

This report and previous year’s analyses are available on our website: Port Valdez Weather Buoy Analysis 2019 – 2022
