Satellite data increases understanding of the effects of climate change, Using 35 years of satellite imagery, researchers have dramatically expanded the database on the effects of climate change on seaweed and seaweed, which provides food and protection for fish and protects the coast from wave damage.
The Landsat Program is a joint effort by NASA and the US Geological Survey, which has been collecting surface data since 1975 but was recently used to monitor algae.
The OSU study is the first to use Landsat data to study algae, large algae that grow in “forests” that form a shelter in shallow sea water.
There are about 30 genera and although they look like plants, they are actually heterocontains related to algae.
It is very interesting to extract technology from other regions and incorporate it into marine science to improve our work, researchers say.
The 35-year record in marine biology is really hard to find. Usually difficult to do boat work, expensive, you need trained and dangerous divers. However, we need long-term data to understand climate change and its impact on populations. Satellite data increases understanding of the effects of climate change.
This is an exponential increase in the amount of information available for Oregon seaweed.
But we haven’t found evidence of a loss of algal population in Oregon since 2014, even though we’re only abroad.
Our results provide images that create news circles and show the need for further research because we don’t really understand algae.
Off the Oregon coast, most of the algae grows in the southern third of the state, with the majority spread over five different reefs.
Algae data, irritated by Landsat imagery for decades, show that canopy areas can vary dramatically from year to year and long-term population trends vary from one reef to another. Satellite data increases understanding of the effects of climate change.
Coral, Rogue, near Gold Beach, has a larger population in 2018, the final year of analysis, than at any time in the last 35 years.
In the years that we examined, three out of five coral reefs are still historically normal population levels. The other has had a small population in the last 15 years, and the fifth has shifted to a population that is slightly less and less variable in the last two decades.
Previously, extensive perennial algae research, Macrocystis pyrifera, showed that high waves in winter had a negative impact on algal populations. However, this study shows the opposite for algae every year. Satellite data increases understanding of the effects of climate change.
The relationship between longer waves and more algae is 100 percent above the basic idea when it comes to algae, the researchers said.
Our study shows that when you change species or geographical areas, you get additional new factors.
Hamilton tried to show that algae are very beautiful, but that is not the main reason why marine biologists are interested in them.
We didn’t learn them because they are beautiful and we like to dive, even though it’s good and we like to dive, researchers say.
Algae are important for ecosystems and human communities that live on the coast.
Algal forests provide nearby ecosystem services and services, including nursery habitats for young rock fish, porcupine fish, and algae.
People need to have access to basic environmental resources that are important to them, and we need to know how these resources change and how these changes affect people, often vulnerable people.
