Kelp Talk
It looks like it could be a small, sparse bed of kelp
I think that is some other kind of coastal vegetation. It looks too bright (green) to be kelp wrack
Wow, that is some of the brightest/densest kelp we have seen
hmm, that is definitely not kelp. It could be an algal bloom or it might be a shoal, sandbar, or other type of shallow water.
Yes, or some other kind of submerged vegetation. This is in Tomales Bay north of San Fransisco
Yes, it looks like a small island
That is the edge of a Landsat scene. You can just hit Next Image when you see those and they will be removed from the system
I don't think so, it looks too far offshore to be kelp. Maybe floating debris or other phytoplankton
yes, seagrass and sand bottom, no kelp
not kelp
I think this is seagrass and other vegetation on mudflats
That is land below the clouds
Yes, those faint shadows are just the water. It's a bit tough to see with this thin cloud cover though
Correct, that is not kelp. These are whitecaps, it must be an very windy day! You generally won't see any kelp in these open ocean images.
that is kelp
Yep, that is kelp
#boats in the middle of the ocean
That one is tough. I think erring on the side of possible makes sense here. Thanks!

No, don't mark those dots. That is a problem with the Landsat data called the "Christmas Tree Anomaly".
I don't think there is any kelp here. It looks like this scene is all land...cloudy land.
Salt ponds? They look similar to massive aquaculture operations you see on satellite imagery from SE Asia and parts of Central America.
wild patterns
#boats and a runway and golf course
Both of those are islands
Although other scientists are using satellite imagery to detect algal blooms in lakes and other water bodies
The type of kelp we are looking for (Giant Kelp) does not grow in inland water bodies. So you can ignore them for this project.

I've been seeing a lot more #kelpy images. Seems like more of the bad scenes have been getting filtered out.
#mudflats in Macquarie Harbour
I'd say island. It looks too bright to be kelp.
agriculture quilt
That looks like the riparian zone around a small stream or river. The green is the vegetation. Not sure exactly where this is though...
Thank you! Right now hitting the "Next Image" button on a bad scene will help filter it out. But a broken image button might be coming soon.
That is massive!
Some sparse patches of kelp on the central coast of California
Those are breaking waves. This must be a pretty wave-exposed area.
