Southern sea otter recovery has come a long way, but there’s still work to be done. 🐾
It absolutely does!!!!! There is so much we still don’t understand! So much to be discovered! So much unknown! So much unexplored territory!
no seriously at what point do we stop saying dinosaurs and start saying prehistoric birds?? is it a matter of time?? a matter of species??? SCIENCE SIDE OF TUMBLR PLEASE HELP

So I will admit I was feeling funny about going to the Field Museum because of the whole “look at display of objects from colonized groups” thing. Especially because of the Black Panther post with commentary on museums.
But boy, the Field Museum really does seem to be doing a fair amount towards rectifying past attitudes and actions. I took these two pictures and there were at least two others I wish I had remembered to take pictures of. I was thrilled to see such obvious mentions of this kind of thing instead of a lack of change or pretending it didn’t happen.
@kaijutegu I’ve been meaning to post these for the past few days, every time I see the BP museum post go by again!
Earth is a place dominated by water, mainly oceans. It’s also a place our researchers study to understand life. Trillions of gallons of water flow freely across the surface of our blue-green planet. Ocean’s vibrant ecosystems impact our lives in many ways.
In celebration of World Oceans Day, here are a few things you might not know about these complex waterways.
The way light is absorbed and scattered throughout the ocean determines which colors it takes on. Red, orange, yellow,and green light are absorbed quickly beneath the surface, leaving blue light to be scattered and reflected back. This causes us to see various blue and violet hues.
Follow the phytoplankton! These small plant-like organisms are the beginning of the food web for most of the ocean. As phytoplankton grow and multiply, they are eaten by zooplankton, small fish and other animals. Larger animals then eat the smaller ones. The fishing industry identifies good spots by using ocean color images to locate areas rich in phytoplankton. Phytoplankton, as revealed by ocean color, frequently show scientists where ocean currents provide nutrients for plant growth.
When we look at the ocean from space, we see many different shades of blue. Using instruments that are more sensitive than the human eye, we can measure carefully the fantastic array of colors of the ocean. Different colors may reveal the presence and amount of phytoplankton, sediments and dissolved organic matter.
About 70 percent of the planet is ocean, with an average depth of more than 12,400 feet. Given that light doesn’t penetrate much deeper than 330 feet below the water’s surface (in the clearest water), most of our planet is in a perpetual state of darkness. Although dark, this part of the ocean still supports many forms of life, some of which are fed by sinking phytoplankton.
Instruments on satellites in space, hundreds of kilometers above us, can measure many things about the sea: surface winds, sea surface temperature, water color, wave height, and height of the ocean surface.
The amount of salt varies depending on location. The Atlantic Ocean is saltier than the Pacific Ocean, for instance. Most of the salt in the ocean is the same kind of salt we put on our food: sodium chloride.
It will most likely have millions (yes, millions!) of bacteria and viruses, thousands of phytoplankton cells, and even some fish eggs, baby crabs, and small worms.
Just 3.5 percent of Earth’s water is fresh—that is, with few salts in it. You can find Earth’s freshwater in our lakes, rivers, and streams, but don’t forget groundwater and glaciers. Over 68 percent of Earth’s freshwater is locked up in ice and glaciers. And another 30 percent is in groundwater.
Just like forests are considered the “lungs of the earth”, phytoplankton is known for providing the same service in the ocean! They consume carbon dioxide, dissolved in the sunlit portion of the ocean, and produce about half of the world’s oxygen.

People horrifically fucking up facts about evolution and genetics too support their stupid beliefs or to seem smart and “rational” is probably one of my big pet peeves
Once I was made of stardust. Now I am made of flesh and I can experience our agreed-upon reality and said reality is exciting and beautiful and terrifying and full of interesting things to compile on a blog! / 27 / ENTP / they-them / Divination Wizard / B.E.y.O.N.D. department of Research and Development / scientist / science enthusiast / [fantasyd20 character]
