The brown color is caused mainly by a kind of phytoplankton called diatoms. The tiny creatures feed on nutrients that pour out of the Columbia River and other smaller waterways. With a large number of diatoms comes a large number of baitfish, which in turn attract humpback whales. Copyright 2022 Nexstar Media Inc.
Why is the ocean brown in Seaside?
Boothe said the brown gooey waves are caused by a diatom bloom. “Diatoms are single-celled plants (phytoplankton) that are found in both fresh and salt water,” Boothe said. “They are one of the most important food sources in the ocean.”
What causes brown surf?
The brown foam seen on our beaches from time to time is surf algae, also known as surf scum. Surf algae are always present in the surf- zone but sometimes there is a population explosion. This is when large amounts of unsightly brown foam make a temporary appearance in the surf and on the beach.
What is the brown stuff on the beach?
Just Diatoms! Diatoms are single-celled plants (phytoplankton) that are found in both fresh and salt water. They are one of the most important food sources in the ocean. In the winter, spring, and early summer, diatoms rapidly multiply in the surf zone.
What washed up on Oregon Coast?
CANNON BEACH, Ore. — An 120-pound dead shark that was nearly 9 feet long washed ashore on the Oregon Coast on Sunday, according to the Seaside Aquarium.

What do brown waves mean?
Rather, it’s an overgrowth of algae, aka an algal bloom, and in the case of the shearwaters, a harmful algal bloom (HAB). Algal blooms occur all over the world. In some places, they do turn the water blood red, which certain religious sects see as a sign of the end times.
Why is Atlantic ocean not blue?
As light bounces off and passes through water, it reflects the color blue back to our eyes, but microscopic algae and tiny sediments known as colored dissolved organic matter muddy the metaphorical waters and cause oceans to appear green, red, or brown.
Why are the waves brown in Seaside Oregon?

Why is the Pacific ocean brown?
When the water looks murky or brown, it means there is a lot of mud, or sediment, in the water. Sediment particles can be so tiny that they take a long time to settle to the bottom, so they travel wherever the water goes. Rivers carry sediment into the bay, and waves and tides help keep the sediment suspended.
Why is the ocean water brown and foamy?
This is brown foam which is seen on our beaches from time to time. It is called surf foam or surf scum. It can be easily mistaken for pollution, but it isn’t. It is a collection of millions of microscopic algae (bloom) and is a natural phenomenon.
Is sea foam sewage?
If you notice foam on the water’s surface or on the beach this is likely to be the result of algae dying off and breaking down. It is very unlikely to be sewage.
Why is the ocean brown and foamy?
Algal blooms are one common source of thick sea foams. When large blooms of algae decay offshore, great amounts of decaying algal matter often wash ashore. Foam forms as this organic matter is churned up by the surf. Most sea foam is not harmful to humans and is often an indication of a productive ocean ecosystem.
Are there sharks in Seaside Oregon?

Are sand dollars dead when they wash ashore?
While the sand dollars are still alive when stranded, they are unable to make it back to the water once the tide recedes. Instead, they are drying up and dying.
Why are there so many sand dollars in Seaside Oregon?
Part of the reason is that there are simply so many just offshore, and part of that reason is because there’s an unusual amount of nutrients pouring down from the Columbia River that feed the plankton of the area – which sand dollars eat. Thus, more sand dollar beds.
How long brown water lasts?
Typically these problems clear up within a couple of hours, but can take as long as several days to return to normal. In temporary situations like this we recommend not using hot water at all if possible, to keep the discolored water from being drawn into your water heater.
