What if we told you that a group of gelatinous animals helps control the planet’s climate? Your disbelief would be salp-able!
Salps are filter-feeding gelata related to pyrosomes that pack up plankton produce into poo pellets that precipitate into the deep, capturing carbon from the atmosphere and tucking it away in the depths of the hydrosphere.
Thanks to local photographers Michelle Manson and Joe Platko for the salp selfies! Joe’s photo on top shows a solitary Pegea confoederata ready to birth the same kind of long chain that Michelle found in her lower photo!
(The pink orbs are the salps’ guts, and these tubular animals are essentially a passing pasta strainer for plankton!)
It’s National Hippo Day, and this is all we got.
The word phytoplanton comes from the greek words phyto (plant) plankton (made to wander) And what they do for the world is amazing! They are a great example of doing SO much even though they are small. Without them we wouldn’t have enough oxygen. The fish and sea life would all most definately die, which would effect food for humans and land animals. It would effect cultures and peace in general, because without sea life many beliefs and practices would be effected as well. Without them the sea animals wouldn’t be able to “breathe”. A good way humans can make sure to keep the phytoplankton around is by making sure we don’t litter, or pour harmful chemicals into the ocean that could kill them. A great place to learn more about this is here:

Nudibranchs are dainty, colorful, voracious ocean predators. And this species figured out how to get two meals for the price of one!
Submitted for your consideration: A team of researchers from more than 20 institutions, boarding two research vessels, heading into the ocean’s twilight zone.
The twilight zone is a dimly lit region between 650 and 3300 feet below the surface, where we’re unfolding the mystery of how tiny ocean organisms affect our planet’s climate.
These tiny organisms – called phytoplankton – are plant-like and mostly single-celled. They live in water, taking in carbon dioxide and releasing oxygen.
Two boats, more than 100 researchers from more than 20 partner institutions, and a whole fleet of robotic explorers make up the EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) team. We’re learning more about what happens to carbon dioxide after phytoplankton digest it.
Phytoplankton have predators in the ocean called zooplankton. They absorb the phytoplankton’s carbon, carrying it up the food chain. The EXPORTS mission will focus partly on how that happens in the ocean’s twilight zone, where some zooplankton live. When phytoplankton die, sometimes their bodies sink through the same area. All of this carries carbon dioxide into the ocean’s depths and out of Earth’s atmosphere.
Studying the diversity of these organisms is important to better understand what’s happening to the phytoplankton as they die. Researchers from the Virginia Institute of Marine Science are using a very fine mesh net to sample water at various depths throughout the ocean to count various plankton populations.
Researchers from the University of Rhode Island are bringing the tools to sequence the DNA of phytoplankton and zooplankton to help count these organism populations, getting a closer look at what lives below the ocean’s surface.
Taking measurements at various depths is important, because phytoplankton, like plants, use sunlight to digest carbon dioxide. That means that phytoplankton at different levels in the ocean absorb and digest carbon differently. We’re bringing a Wirewalker, an instrument that glides up and down along a vertical wire to take in water samples all along its 500-foot long tether.
This journey to the twilight zone will take about thirty days, but we’ll be sending back dispatches from the ships. Follow along as we dive into ocean diversity on our Earth Expeditions blog: https://blogs.nasa.gov/earthexpeditions.

One month down
Cultural differences
Language barrier
On Friday, my first month in Costa Rica ended and marked the beginning of my second month here. Over the course of this month, I have noticed a lot of differences between Costa Rican culture and U.S. culture, although there are probably more that I have not noticed because I have not thought about them. Personal space and your personal bubble do not exist in the way they do in the U.S. It is common to hug and kiss people on the cheek as a sign of greeting and farewell, which as someone who likes their personal bubble, is taking a bit of time to get used to. It is very common for men to catcall, whistle, honk their horns, and stare at women walking, although every time that I have seen it, that's all it was. It makes me think that instead of men just lacking in all forms of self control, it is more of a cultural norm to do it and it would be out of place for men not to do it. Although, it still makes my female friends from the U.S. very uncomfortable for obvious reasons. Rules of the road really just seem like suggestions and it seems that drivers make up their own rules as they go, including motorcycles and scooters that always pass cars, buses, trucks, SUVs, etc... when they shouldn't. Most classes at the university are only once a week and there is a lot less busy work and a lot more group work. It is acceptable for people to show up late for classes and events (tico time), however, it does not apply to my science classes.
By far, my biggest struggle has been the language barrier. Looking back at a month ago, I can tell that there has been at least a subtle increase in my proficiency with Spanish. I try to listen and follow my professors, my parents, and other people that I encounter, but at times I can't understand what they are saying, although my listening skills are still a lot better than my speaking skills. I try to talk as much as possible but my problems are when I don't a word I need and cannot get around (although today I had a conversation about my opinion genetic modification with classmates for fun and it went really well) and if I don't have anything to say, I usually don't say anything. To mediate this, I've tried to force myself to talk more with mixed success. But I have learned that even if I understand 95% of what everyone says, the only way my speaking will improve is if I speak as much as I possibly can, knowing that I will make a lot of mistakes in the beginning.

July. Long known across the U.S. for fireworks, barbecues, and a desire to stay cool any way we can. Whether it’s air conditioning, swimming pools, beaches or popsicles, the dog days of summer are often reminders that as humans, our comfort depends on an experienced ambient temperature roughly somewhere between 59 and 77 degrees (Fahrenheit).
But what if, instead of 77, it’s a full 40 degrees more: 117 degrees, like it was in California on July 6? Or 105, like it was in Japan last week? Then, it’s more than an issue of comfort; our lives depend on finding a way to stay cool, and in fact more than a hundred people have perished in heat-related deaths globally already this year.
Life in this new age, the Anthropocene, is marked by many things, including a human-caused increase in global heat, commonly referred to as global warming, or climate change. Risk from heat (or wildfires, or floods) is no longer something we have to rely on the overwhelmingly strong scientific consensus about global warming to tell us; every year, climate change impacts are becoming more and more obvious to everyone, whether you have a degree in climate science or not.
Weather and climate are different. Weather is what happens on a day-to-day basis. Climate is the range of weather that we expect and consider normal (i.e., summer is hot) – but normal is changing.

We’re now up to over 400 consecutive warmer-than-average months and counting. Carnegie Museum of Natural History’s collections, which span more than 140 years, can help show these shifts in many ways. One of the most important things we can do is to make connections and show the relevance between the basic scientific principles underlying natural phenomena and the evidence all around us; between what’s happening globally and what’s happening locally.
Photo: The growth of plants collected today versus 100 years ago in the same locations, shown in We Are Nature, corroborates the observation of increasingly earlier springtime by documenting earlier maturation of these species.
The globe’s increasing heat is a result of fossil fuel use, food production, and our land use practices. We need energy and food, of course; but it’s critical that we recognize that the systems we impact also impact us. It’s not just our actions, but our interactions with the world around us that are the story. To understand what’s happening and improve our interactions with nature, we have to look at the big picture, and work to meet our needs in ways that minimize disruption to the overall system.
As summer heat waves get longer, more numerous, and more intense (and it seems the whole world is on fire, with deadly fires everywhere from California to Greece to inside the Arctic Circle) one connection is obvious: our need to be cool.

The National Science Foundation (NSF)—the major funding agency for basic science—has canceled all grant review panels this week to comply with an executive order from the new administration. This is where independent panels of scientists discuss grant proposals they’ve reviewed for scientific merit and recommend which projects get funded to NSF project managers. A LOT of work goes into setting up and scheduling grant reviews. It will take time to reschedule these panels, delaying key decisions for many promising projects. This will wreak havoc on science grant funding for months to come.
Put simply, this action along with the halting of NIH-funded grants are blatant and reckless political attacks on science, from an administration that seeks blinding loyalty.
Blog dedicted to phytoplankton. Phytoplankton are microscopic organisms that are responsible for half of the photosynthesis that occurs on Earth. Oh, and they look like art... Follow to learn more about these amazing litter critters! Caution: Will share other ocean science posts!Run by an oceanographer and phytoplankton expert.
