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.

Birds are known to be highly social and visual animals, and penguins are not the exception, as they live in dense colonies. Yet no specific visual feature has been identified to be responsible for individual recognition in birds. Now, researchers demonstrate that african penguins (Spheniscus demersus) can recognize their each others using their ventral dot patterns.
Researchers placed a experiment at the Zoomarine Marine Park, in Rome, Italy, to test how penguins will react to a model with plain with no dot penguin, and to penguins with dots, to find out penguins actually could visually recognize the dots of their lovers and friends in the zoo.
Penguins rely strongly on their ventral dot patterns for individual recognition, and may have holistic representations of other penguins in the colony. In this video below, an african penguin named Gerry appears to recognize his mate, Fiorella (left), in an individual recognition experiment.
These findings suggest that african penguins may rely on a more holistic visual representation of their partner, which includes both the ventral dot patterns and their partner's facial features. Notably, these abilities are not dependent on the ability of a pair to produce offspring together. Nemo and Chicco, male partners, showed the same preference for each other as other penguin partner pairs, suggesting that the ability to distinguish the partner from others is driven simply by the special bond developed between nesting partners.

This past weekend marked the first anniversary of the launch of NASA’s latest ocean color satellite, PACE 🛰️! Happy birthday PACE!
As our planet warms, Earth’s ocean and atmosphere are changing.
Climate change has a lot of impact on the ocean, from sea level rise to marine heat waves to a loss of biodiversity. Meanwhile, greenhouse gases like carbon dioxide continue to warm our atmosphere.
NASA’s upcoming satellite, PACE, is soon to be on the case!
Set to launch on Feb. 6, 2024, the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission will help us better understand the complex systems driving the global changes that come with a warming climate.
While a single phytoplankton typically can’t be seen with the naked eye, communities of trillions of phytoplankton, called blooms, can be seen from space. Blooms often take on a greenish tinge due to the pigments that phytoplankton (similar to plants on land) use to make energy through photosynthesis.
In a 2023 study, scientists found that portions of the ocean had turned greener because there were more chlorophyll-carrying phytoplankton. PACE has a hyperspectral sensor, the Ocean Color Instrument (OCI), that will be able to discern subtle shifts in hue. This will allow scientists to monitor changes in phytoplankton communities and ocean health overall due to climate change.
With PACE, scientists will be able to tell what phytoplankton communities are present – from space! Before, this could only be done by analyzing a sample of seawater.
Telling “who’s who” in a phytoplankton bloom is key because different phytoplankton play vastly different roles in aquatic ecosystems. They can fuel the food chain and draw down carbon dioxide from the atmosphere to photosynthesize. Some phytoplankton populations capture carbon as they die and sink to the deep ocean; others release the gas back into the atmosphere as they decay near the surface.
Studying these teeny tiny critters from space will help scientists learn how and where phytoplankton are affected by climate change, and how changes in these communities may affect other creatures and ocean ecosystems.
The PACE mission will offer important insights on airborne particles of sea salt, smoke, human-made pollutants, and dust – collectively called aerosols – by observing how they interact with light.
With two instruments called polarimeters, SPEXone and HARP2, PACE will allow scientists to measure the size, composition, and abundance of these microscopic particles in our atmosphere. This information is crucial to figuring out how climate and air quality are changing.
PACE data will help scientists answer key climate questions, like how aerosols affect cloud formation or how ice clouds and liquid clouds differ.
It will also enable scientists to examine one of the trickiest components of climate change to model: how clouds and aerosols interact. Once PACE is operational, scientists can replace the estimates currently used to fill data gaps in climate models with measurements from the new satellite.
With a view of the whole planet every two days, PACE will track both microscopic organisms in the ocean and microscopic particles in the atmosphere. PACE’s unique view will help us learn more about the ways climate change is impacting our planet’s ocean and atmosphere.

Pyrosomes are colonial tunicates made up of thousands of individuals known as zooids. Each zooid is housed in the common gelatinous tunic that makes up the larger cylindrical “body” of the pyrosome. Zooids filter phytoplankton through branchial baskets by creating feeding currents through the tunic. Although each zooid is only a couple of millimeters in size, pyrosomes can reach up to several meters in length. While alive, these organisms spend the majority of their time in the upper water column, but their remains have been found as deep as 4,000 meters (13,120 feet), where they provide food for a variety of deep-sea animals.
Pyrosomes are bioluminescent, producing brilliant blue-green light. Each zooid can detect light and emit light in response, creating waves of bioluminescence up and down the organism’s body. The bioluminescence of one pyrosome can trigger others in surrounding waters, producing beautiful light shows. The name Pyrosoma comes from the Greek term meaning “fire body.”
Galiteuthis phyllura, also known as the cockatoo squid, lives in the North Pacific from 200 to over 1,000 meters (660 to 3,280 feet) deep. This species has a transparent body and photophores, or light organs, under their eyes. We often encounter them hanging horizontally in the water column with their arms raised above their heads.
With marine life and ecosystems facing a rising tide of threats, the ocean exploration community needs nimble, cost-effective tools for measuring and monitoring ocean health. MBARI’s Control, Modeling, and Perception of Autonomous Systems Laboratory, known as the CoMPAS Lab is up to the challenge.
MBARI scientists and engineers build and adapt advanced technology that enhances ocean data collection. Led by engineer Giancarlo Troni, the CoMPAS Lab team develops scalable marine technology that can easily be modified for use in a wide variety of vehicles and platforms.
Working with other teams across MBARI, the CoMPAS Lab leverages vehicles like the MiniROV to deploy and test new tools in Monterey Bay's submarine canyon and then adapt them for other mobile platforms. By sharing open-source design specifications and advanced algorithms with the wider ocean exploration community, we hope to expand access to MBARI’s engineering innovations.
MBARI technology is transforming what we know about the ocean and its inhabitants. Our scientists, engineers, and marine operations staff work together to create innovative tools for a more sustainable future where autonomous robots and artificial intelligence can track ocean health in real time and help us visualize ocean animals and environments. Studying our blue backyard is revealing our connection to the ocean—how it sustains us and how our actions on land may be threatening its future.
We’re spotlighting various teams at MBARI to showcase the different ways we’re studying the largest environment on Earth. We hope this series inspires a new generation of ocean explorers. Dive in.
Next month will be the one year anniversary of the PACE launch!

Check out my new post!
http://becausephytoplankton.blogspot.com/2018/09/diatoms-algae-in-glass-houses.html
Very cool. My lab group also works with Emiliania huxleyi and EhVs.
Don’t underestimate the importance of phytoplankton!
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.

Despite deep-sea environments covers about half of the Earth’s surface and is home to a vast range of species, little is known about these environments, and mining could have long-lasting and unforeseen consequences, not just at mining sites but also across much larger areas.
According to a study published in scientific journal Frontiers in Marine Science, which is the first to give a global overview of all current plans to mine the seabed, in both national and international waters, and looks at the potential impacts including physical destruction of seabed habitats, creation of large underwater plumes of sediment and the effects of chemical, noise and light pollution arising from mining operations.
Rising demand for minerals and metals, including for use in the technology sector, has led to a resurgence of interest in exploration of mineral resources located on the seabed. Such resources, whether seafloor massive sulfides around hydrothermal vents, cobalt-rich crusts on the flanks of seamounts or fields of manganese nodules on the abyssal plains, cannot be considered in isolation of the distinctive, in some cases unique, assemblages of marine species associated with the same habitats and structures.
Some operations are already taking place, generally at relatively shallow depths near national coastlines. The first commercial enterprise, expected to target mineral-rich sulfides in deeper waters, at depths between 1,500 and 2,000 m on the continental shelf of Papua New Guinea, is scheduled to begin early in 2019.
