Kelp Talk
Hey, I used to live near there! I would guess that the rivers are just unusually silty, maybe a heavy rain recently.
It's dead plant life floating in the ocean currents, after a storm. When they're new they're green, but this raft has been floating a while.
Just looks like clouds to me, sorry!
Yup! Contrails are surprisingly rare to see, given there's a major airport in the Cali study area.
They're errors in the satellite images, you can safely ignore them.
Clouds. 😃 Snow will always been that vivid cyan-blue.
Images that are marked as 'no kelp' are classified very few times before being taken out of active circulation, so you are rejecting them.
Pretty sure there's some algae under those clouds. Tasmania data has me looking for signs of green very carefully, there's not much of it!
Kelp harvesting! Take a little bit off the top, and it grows right back if the kelp is healthy and you don't do it too often.
I think I see what you're talking about, maybe some very faint kelp.
Yup, we're looking at Tasmania and California right now, this is Tasmania.
I think that's algae, not kelp? :\ Quite impressive either way!
No kelp, but that's a huge #algae bloom inland!
Is that some elusive Tasmania kelp, or maybe rocks/reef off the coast? It doesn't look quite right.
Glad you're enjoying it! It's a pretty neat way to explore the coastline.
Very cold clouds look blue in these images, we're looking at some very cold, probably rainy, clouds here.
It's the test phase of an artificial reef for kelp, see: http://blog.floatingforests.org/2015/01/14/kelp-forest-on-artificial-reef/
Yes! Some very narrow forests.
A neat bed of #kelp growing south east of South Coronado island.
Both! Always circle any kelp you can see, and mark 'clouds' when there are clouds that are potentially interfering with kelp marking.
Not kale, but it is kelp. 😉 Check out: http://blog.floatingforests.org/2015/01/14/kelp-forest-on-artificial-reef/
Lots of neat cloud formations happen on coastlines and around islands. Lucky us the clouds don't always hug the coastline.
Tons of kelp! The big green area on the right is all kelp, the coastline is just a little out of frame.
They're boats!
Rice maybe? They flood the fields at certain growing times for rice.

Kelp of a sort! There was a storm sometime between October 22-29th, this is a free floating chunk of kelp lost at sea. This is from Oct 29:
Snow everywhere! Even in southern California, the mountains have a good cover of snow in January. (If the clouds cooperate...)
Fire! Quite a lot of smoke here, and you can see a few red flames on the edge.
La Jolla looking particularly amazing #kelp
This particular bit of island coast is my favorite area in the current data set, there isn't always kelp here, but when there is, WOW!
What a huge bloom, too!
AKP000mhuo Got these two back to back and thought I had a bit of deja vu. Just a bit to the left, similar cloud cover.. and 3 years apart!
PS See http://www.cyclonecenter.org/ for more clouds 😄
Looks like a rather small storm cell, not big enough to be a hurricane. I checked the records, no major or minor storms in Cali at the time.
--attention to how land-features look in these images to say for sure, reasoning from first principles here. 😃
Snow's possible in these mountains in April, could be some fresh snow lingering on the northern slopes. I haven't been paying enough --
We're looking at 345 band images on FF. So there's something dark in the red 5 band, which is infra-red, brighter in near IR and visual.
The images we're looking at aren't all visual light images. Nice readable explanation: http://www.satelliteimpressions.com/landsat.html
I think those are actually waves, sometimes they show up very strongly, other times not at all. Very odd looking image!
The green spot down in the bottom right is definitely #kelp! Sometimes the coastline is just out of the image...
#kelp, clouds, and the edge of the landsat image.
-- and doesn't really have any structure to it.
Definitely kelp! Check out AKP000gp3b for some side by side algae and kelp, the kelp is clumpy and distinct, the algae is stringy/swoopy --
They come in red, green and blue varieties, sometimes all in one frame!
That's an error in the satellite imagery. You can tell because of how perfectly straight the edges are, and it follows the scan lines.
So rare to see lots of kelp on this island! I've never seen that bed to the south before.
Impressive runoff, no kelp though.
#kelp And here we are again, even brighter this time!
Hello Tasmania! Do we have new data? I'm seeing about half and half Tasmania and California coastlines today.
Hello lovely #kelp! 2.9km^2 of it!
Even California is sometimes green. 😉
What a beautiful forest!
Hah! I can see my house from here! No kelp on these beaches, sadly.
Massive #kelp forest just off San Nicolas Island
Google Earth says yes! It really is a lovely bed of kelp.
Very curious! The data is from 1985, I wonder if there was markedly less ocean going activity in the area to disturb the kelp?
Very bright #kelp!
That's kelp! The distance it grows from shore depends on how steep the ocean floor drops, here it's quite steep so it's very close to shore.
Wow! #Kelp growing all around a tiny island too small to see, just off the coast.
Bright #kelp peeking out between the clouds
Is this all actually #kelp? Almost looks like it's encroaching on the shore on the west side.
#kelp out in the middle of nowhere?
