A wide selection of video resources for every audience
Dungeness crab is one of the most valuable commercial fisheries on the West Coast. As ocean acidification changes the chemistry of our oceans, scientists and fishermen are just beginning to understand how it will impact this important species. “Even though they’re incredibly tough,” says research ecologist Paul McElhany, “they are also susceptible to environmental conditions.”
This PBS short takes a look at how ocean acidification has affected shellfish farming families in the Pacific Northwest. Shellfish growers and scientists speak about their experiences learning about and adapting to ocean acidification, why the issue is so critical to them, and what can be done to ameliorate the problem in the future.
This two-minute video created by the North Carolina Aquarium at Fort Fisher provides a short and sweet summary of the chemistry of ocean acidification. The animation makes it easy to visualize just why shellfish and coral are struggling in more acidic conditions.
Plymouth Marine Lab produced this 12-minute video, called “Ocean Acidification: Connecting science, industry, policy and public.” Beautifully made, the video provides an overview of the science of OA, how it might affect marine dependent communities around the world, current research on OA, and the process of creating policy to tackle OA and its impacts.
With stunning underwater footage, the German research network BIOACID examines the effects of acidification on the life and biogeochemical cycles in the ocean – and on all those who depend on it. Many plants and animals that build their shells or skeletons of calcium carbonate are at serious risk, because they need more energy to maintain growth in more acidic water; the development of important food fish can also be affected. Organisms that convert carbon dioxide into energy by photosynthesis, however, could benefit. In addition, certain species are able to adapt to new conditions in the long run. The roles in the marine food web are redefined, while other factors such as rising temperatures, loss of oxygen, eutrophication, pollution or overfishing might further influence the effects of ocean acidification.
Marine organisms utilize two forms of calcium carbonate to build their shells and skeletons – aragonite and calcite. Ocean acidification causes a decrease in the saturation state (essentially the amount available in the water) of these forms of calcium carbonate. This 30-second video shows the changes in aragonite saturation state around the world between the years 1800-2100. High saturation state is indicated with green; low saturation state with red. The white dots show where major coral reef systems are in the world.
In this talk, Dr. Triona McGrath explains how our oceans are changing due to increasing levels of carbon dioxide in the atmosphere and how it will impact our marine life. Triona shares her thoughts on ocean acidification and explain why it is the evil twin of climate change.
About one billion people rely on seafood as a primary source of animal protein.
Projects led by the International Atomic Energy Agency, or IAEA, are using nuclear and isotopic techniques to examine how marine organisms might respond to future ocean acidification caused by harmful carbon dioxide emissions- protecting our marine species, livelihoods, and economy in the process.
The International Atomic Energy Agency also released this video, featuring Bill Dewey of Taylor Shellfish Farms, who has worked closely with Global Ocean Health on OA issues.
‘Sea Change: The Pacific’s Perilous Turn’
The Seattle Times explores how ocean acidification could alter the seas on a scale almost too big to fathom.
West Coast fishermen, others in the seafood business, a scientist and a manager reflect on the potential “big change” that a changing climate may bring to fisheries. The 13-minute documentary is produced by Oregon Sea Grant with partial funding from the NOAA Climate Program Office.
Dr Ruth Gates, our own Board member and a University of Hawaii marine biologist speaks about creating designer coral reefs to combat the effects of warming and OA.
A short animation about the potential impact of ocean acidification on sea life in the Gulf of Maine. Produced with support from Maine Sea Grant, Dalhousie University, MEOPAR (Marine Environmental Observation Prediction and Response Network), NERACOOS (The Northeastern Regional Association of Coastal Ocean Observing Systems) and NECAN (Northeast Coastal Acidification Network).
Saving Paradise is a documentary series created to educate the public on the issues and potential solutions for Cape Cod’s wastewater challenge. There’s excellent footage of time-lapse water filtration by oysters. Acidification works differently on the East Coast: instead of being driven by coastal upwelling, it’s affected by freshwater intake and wastewater (particularly nitrogen) discharge. That, along with the excellent information on the filtration properties of oysters, is why we’ve included this video.
