For Two Years, The Bering Sea Has Been Largely Without Winter Ice, A Development Scientists Modeling

As Bering Sea ice melts, Alaskans, scientists and Seattle’s fishing fleet witness changes ‘on a massive scale’
With winter ice largely gone for two years, a food chain is at risk. What lies ahead for a body of water that produces some of the world’s biggest seafood harvests and helps sustain communities ranging from Alaska to Seattle,...

For two years, the Bering Sea has been largely without winter ice, a development scientists modeling the warming impacts of greenhouse-gas pollution from fossil fuels once forecast would not occur until 2050.

This ice provided a giant platform for growing algae at the base of the food chain, and has been a significant contributor to the remarkable productivity of a body of water, stretching from Alaska to northeast Russia, that sustains some of the biggest fisheries on the planet.

Guess hoo-hoo it is 🦉

The owlfish, named for the size of its large eyes relative to its head, lives throughout the North Pacific. These species are in the family Bathylagidae and are relatively common in the deep sea, living at depths of over 6,000 meters (19,685 feet). In Monterey Bay, we observe these fish between a few hundred meters to over 2,000 meters (6,560 feet)

Baby Loggerhead Turtle At Home In The Sargassum In The Gulf Stream Current, Where It Will Spend Roughly

Baby loggerhead turtle at home in the sargassum in the Gulf Stream current, where it will spend roughly 5 years, finally being large enough that many animals won’t be able to eat! Sea Turtles have a very difficult life, most of which never make it to maturity and reproduce! Our own existence here on earth as a species is responsible for the death of many beautiful creatures including the sea Turtles, due to mistakes of the past! We have the knowledge, technology and some the drive to fix this, but will we make necessary changes to put our beautiful planet into a sustainable direction? I MOST DEFINITELY WILL! Please join me as our planets future and all creatures are dependent on it! Be the change the world needs! @jim_abernethy #beautiful #babyturtle #gorgeous #cute #precious #underwater #saveturtles #saveoceans (at Jim Abernethy’s Scuba Adventures & Marine Life Art Gallery)

FROM PANAMA TO MARIANA TRENCH:  FEMALE WHALE SHARK MADE A RECORD!

FROM PANAMA TO MARIANA TRENCH:  FEMALE WHALE SHARK MADE A RECORD!

For two and a half years, scientists followed the movements of Anne, a whale shark, during which she swam from the coast of Central America to the Mariana Trench.

In 2011, researchers put a transmitter on Anne near Coiba Island in Panama. In the following 841 days, Anne’s transmitter sent a signal to the ARGOS satellite when it swam close to the surface. These trasmitter allowed the team to follow its movements to the south to the Galapagos Islands and throughout the Pacific to the Mariana Trench, to the south of Japan and the east of the Philippines. She traveled a distance of 20142 kilometers.

The finding reinforces the position of the whale shark as one of the animals that travels most, along with leatherback turtle, gray whale and the arctic tern. In 2016, the IUCN cataloged the species for the first time as threatened. Biologists calculate that tropical and subtropical seas have less than half of whale sharks that they had 75 years ago, which increases the urgency of their protection.

This past weekend marked the first anniversary of the launch of NASA’s latest ocean color satellite, PACE 🛰️! Happy birthday PACE!

Sharpening Our View of Climate Change with the Plankton, Aerosol, Cloud, ocean Ecosystem Satellite

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.

The darkest green correlates to higher levels of change. Black dots on the map represent areas where chlorophyll levels also changed. Credit: NASA/Wanmei Liang; data from Cael, B. B., et al. (2023)

Earth’s ocean is becoming greener due to climate change. PACE will see the ocean in more hues than ever before.

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.

Phytoplankton play a key role in helping the ocean absorb carbon from the atmosphere. PACE will identify different phytoplankton species from space.

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.

Climate models are one of our most powerful tools to understand how Earth is changing. PACE data will improve the data these models rely on.

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.
