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.

More artwork of my characters, featuring Crystal, that was made for me by my friend @jewelsart7 about 3 years ago. (Ik, I’m super late) She has a cute anime-like art style and you guys should go check out her work. 😊 Thanks again Jewels! 🔹 https://www.instagram.com/p/CH00q2zD1kU/?igshid=1vcv5e8lwmwlw
Finished up the inking yesterday. I experimented with adding hatching! This is something that I’ve been wanting to try, but I wasn’t sure about how it would turn out. I got out of my comfort zone and just did it anyway. Hope you like it!
I've finished inking it in. The amount of times my new micron bled out more ink than I wanted is ridiculous though. At least the line work looks decent overall.⠀ 🔷⠀ I started school again two weeks ago and it's been difficult to find a new groove that works for me. I'm settling into this new schedule slowly but surely, so I hope that I will be able to make more time for drawing in the near future.⠀ 🔷⠀ Enough with my mini vent. I hope you enjoy more details of my OC Helyna at "school." 😊
I’ve seen many iterations of yin yang characters and I tried making a pair; They turned out to be a sun god and moon goddess. And tbh I didn’t finish the second one because the face looked so good, I was afraid of messing it up. 😅 Enjoy~
