PODCAST SEGMENT 1: "Scientists like Ole Humlum and Murray Salby noticed that temperatures often rise before COâ levels go up, by about 6 to 12 months. Thatâs like saying the oven heats up before you turn it onâŚ"

Just as highways experience traffic on land, the ocean experiences its own daily commute. đâ
â But instead of cars, this commute involves tiny aquatic plantsâphytoplanktonâthat soak up carbon dioxide produced by burning fossil fuels, shielding us from the harmful impacts of climate change. And the data provided by Biogeochemical-Argo (BGC-Argo) floats gives us more insight into how this ocean âcarbon superhighwayâ works. â
The carbon superhighway, also known as the âbiological pumpâ, is a process that transports carbon dioxide from the atmosphere down into the deep sea. Phytoplankton first take up carbon dioxide at the oceanâs surface into their bodies via photosynthesis and then are eaten by tiny animals called zooplankton. The dead bodies and waste products of phytoplankton and zooplankton, as well as fragments of other dead organisms, all sink through the water column. As the particles fall, they are eaten up in the deep ocean and transformed into carbon dioxide. That carbon dioxide gets trapped in the deep water layers, staying out of contact with the atmosphere for a few thousand years. â
Understanding the carbon superhighway is important because the ocean is one of Earthâs biggest carbon dioxide storehouses, soaking up about 25 percent of the total human carbon emissions per year. This is due in no small part to the biological pumpâs work in transporting atmospheric carbon dioxide to the deep ocean. However, as conditions in the ocean alter with climate change, responding shifts in plankton populations will influence just how effective the biological pump continues to be. The slower the carbon superhighway, the less carbon the ocean can store, and the faster our planet warms.â â Thatâs why the real-time information collected by BGC-Argo floats is so important: by giving us a window into the carbon superhighway and other ocean processes, these floats are helping scientists to better understand and predict the impacts of climate change, to improve ocean health.

Robot on a mission đ¤â â Â
The sheer expanse of the deep sea and the technological challenges of working in an extreme environment make deep-water ecosystems difficult to study. By building on 25 years of engineering innovation, MBARI has developed a solution for long-term monitoring of the abyssal seafloor: Benthic Rover II.â â About the size of a small car, Benthic Rover II travels across the muddy seafloor taking photos and measuring how much oxygen bottom-dwelling animals and microbes are using over time. This autonomous robotic rover has been continuously operational at Station M, an MBARI research site located 225 kilometers (140 miles) off the coast of central California and 4,000 meters (13,100 feet) below the oceanâs surface.â â Â
A new study published in Science Robotics details the development and proven long-term operation of this rover. The information gathered by Benthic Rover II at Station M has helped scientists understand how carbon cycles from the surface to the seafloorâdata fundamental to understanding the impacts of climate change on the ocean.

Can soil photosynthesis help us mitigate climate change? Climate change is one of the most pressing issues of our time, and we need to find innovative ways to mitigate its effects. One potential solution that is gaining traction is enhancing soil photosynthesis to convert atmospheric carbon into soil carbon. This process could help us sequester carbon in the ground, where it would be less likely to enter the atmosphere and contribute to climate change. Let's take a closer look at how this process works and why it could be an important tool in our fight against climate change. Soil photosynthesis is a process by which plants use sunlight to convert atmospheric carbon dioxide into carbohydrates that are then stored in the soil. This process can help to mitigate climate change in two ways. First, it sequesters carbon in the ground, where it is less likely to enter the atmosphere and contribute to greenhouse gas emissions. Second, enhanced soil photosynthesis could lead to increased plant growth, which would further sequester carbon and also result in more green space that can help cool the planet by reflect sunlight. There are a number of ways to enhance soil photosynthesis, including using biochar, increasing nitrogen levels in the soil, and using cover crops.Biochar is a type of charcoal that can be added to the soil to increase its ability to sequester carbon. Studies have shown that biochar can increase soil fertility and water-holding capacity while also reducing greenhouse gas emissions. Increasing nitrogen levels in the soil can also enhance photosynthesis by increasing the rate at which plants convert atmospheric carbon dioxide into carbohydrates. This can be done through a process called nitrogen fertilization, which involves adding nitrogen-rich materials like manure or compost to the soil. Finally, using cover crops can also help enhance photosynthesis by providing a living mulch that helps protect and nurture young plants. Cover crops can also increase water infiltration into the soil and reduce erosion. Conclusion: As we search for ways to mitigate climate change, enhancing soil photosynthesis could be a key piece of the puzzle. #carboncycle (at ecoplanetfarm) https://www.instagram.com/p/CkcSPOBJpZh/?igshid=NGJjMDIxMWI=

Carbon Cycle
The Carbon Cycle is a very well studied process that has been going on since the beginning of life on earth. Carbon much of the time is considered the âbackboneâ of organic life, and that really holds true when broken down from a chemistry standpoint. The carbon cycle allows us to observe how carbon moves through different mediums as fuel and bi-products from other cycles that bring carbon right back to where it started. Carbon is located in the atmosphere where it is then transferred to the biosphere through a familiar process known as photosynthesis. Basically, plants use energy from the sunlight to convert carbon dioxide to sugar molecules by pairing with hydrogens and oxygens from water molecules. Primary consumers now use the plant as food, ingesting those sugar molecules. Animals then respirate, excrete, and decompose back into the earth and atmosphere to complete the cycle. Carbon is stored both in the ocean and within different layers of the earthâs crust. In fact, the coal and fossil fuels that we use today contain carbon from ancient plants and animals that lived millions of years ago. Burning these fossil fuels releases carbon dioxide back into the environment where the cycle once began. Humans have made an impact on the carbon cycle, causing it to slightly change. We put mass amounts of carbon dioxide into the atmosphere along with mining tons of limestone in order to make concrete. An abundance of carbon dioxide in the atmosphere is not a good thing, it causes a phenomenon known as ocean acidification caused by the oceans absorbance of carbon dioxide from the atmosphere. This messes with the balance of chemicals within the ocean water which give some species of fish a harder time than others.
