Health scares

Regrets?

I've already written one entry reflecting on how my family is doing without me and how I am doing without all of my family and friends. I've had to deal with a number of things that have happened at home.

Shortly before I left the United States, my grandfather faced a few health scares. By the time I left, everything had almost past, aside from some minor things. I knew there was a possibility that it could get worse while I was abroad, but I also knew that going abroad would not change any outcome.

Then, almost a month and a half ago, my family had to put one of our dogs to sleep. It was very sudden and everything happened in a few days. What made this more surprising is that our oldest dog is clearly showing his age and we all knew it was possible that I may not see him again, but our other dog is a little bit younger, but he always acts like a puppy so you would never know that he was ten years old. I even remember telling him that I didn’t have to worry about him because it seemed like he was in perfect health. Of course, I feel guilty about saying this, but there is no way I or anyone else could have known what was going to happen.

A few weeks before that, my dad broke his ankle and leg, and would be out of work for weeks. For me, the biggest impact this had was related to money, since my dad is the main bread winner in our family by a mile and it's not like we are rich or very comfortable to begin with. Now, today (Mother's Day in the U.S.), my mom called me because something else happened and my dad has been in critical condition all day and at this point, there is still a lot of uncertainty. It is harder to deal with since I am abroad, especially since a lot of people at SU have finished the semester and have been able to go home.

I think that all of this is plenty of reason to regret going abroad.....but I don't. Even though I lot has happened and is still happening, there is not much I could have done if I was home. More than likely, all of this would have still happened because stuff just happens in life. Don’t get me wrong, it is harder being abroad and being about from all of my friends and family but right now, I'm just reminding myself that stuff like this happens in life and often under the worst of circumstances (not that there is a best of circumstances).

Blooms in the Baltic

Every summer, phytoplankton – microscopic plant-like organisms – spread across the North Atlantic, with blooms spanning hundreds and sometimes thousands of miles. Nutrient-rich, cooler waters tend to promote more growth among marine plants and phytoplankton than is found in tropical waters. Blooms this summer off Scandinavia seem to be particularly intense.

On July 18, 2018, the Operational Land Imager (OLI) on Landsat 8 acquired a natural-color image of a swirling green phytoplankton bloom in the Gulf of Finland, a section of the Baltic Sea. Note how the phytoplankton trace the edges of a vortex; it is possible that this ocean eddy is pumping up nutrients from the depths.

Though it is impossible to know the phytoplankton type without sampling the water, three decades of satellite observations suggest that these green blooms are likely to be cyanobacteria (blue-green algae), an ancient type of marine bacteria that capture and store solar energy through photosynthesis (like plants).

In recent years, the proliferation of algae blooms in the Baltic Sea has led to the regular appearance of “dead zones” in the basin. Phytoplankton and cyanobacteria consume the abundant nutrients in the Baltic ¬and deplete the oxygen. According to researchers from Finland’s University of Turku, the dead zone this year is estimated to span about 70,000 square kilometers (27,000 square miles).

Marine Life of the Maritime Provinces, Canada

After months of work and waiting, here is at long last the full MARS commission. MARS (Marine Animal Response Society) is active in the Maritime Provinces of Canada, and is called upon whenever a marine creature is found dead or in distress. These illustrations will be used to educate their volunteers and assist in making species identifications during strandings or at sea.

With 42 separate illustrations, this is my largest project to date - quite a load of work! But it was an absolute pleasure to do. I got to paint animals I have never painted before, as well as revisit some old friends. The diversity of species found in this one area is impressive and made for varied painting.

I’m pretty pleased seeing them all together like this, and I hope you’ll enjoy them too! 

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.
