Changing main blog now. Everything before this is my study abroad experience in Costa Rica

Every once in a while, sanctuary researchers get a treat – like getting to see this tiny baby octopus! 🐙 . 

Each summer, researchers conduct expeditions in our West Coast sanctuaries as part of the ACCESS conservation partnership. Researchers get to see creatures big and small when conducting surveys in places like Greater Farallones National Marine Sanctuary!

Announcement!

With only a few days until Valentines day it is my scientific duty to inform you all that if you don't have a valentine yet, an algal cell will be your valentine. They will be assigned automatically and love you with all their chloroplasts. You may not opt out, but a platonic algae-mate will be assigned to those who are not romantically inclined.

Meet your new alBAE 💚💚.

Showing off those glide and pivot skills 😶‍🌫️⁠

Fishes in the family Macrouridae, also known as rattails, can glimpse even the faintest flickers of bioluminescence—the “living light” produced by deep-sea animals. Their keen eyesight reveals prey, like fishes and squid, darting in the waters above the seafloor.⁠ ⁠ A rattail relies on other senses, like smell and touch, to find a meal too. It has a nose for rotting carrion, and sensitive barbels on its chin detect small crustaceans or worms wiggling in the mud below.

This Type of Algae Absorbs More Light for Photosynthesis Than Other Plants

An obscure and ecologically successful group of algae, known as cryptophytes, have evolved pigments that capture light where chlorophyll cannot, Dudycha and colleagues report in a series of recent papers. The extra energy absorption from more wavelengths of light has allowed these algae to thrive in a variety of diverse environments, from oceans to streams to ponds to mud puddles.

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.

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.

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)
