The study of the chemistry of the ocean and its processes, such as the carbon cycle and nutrient cycling.
Ocean Chemistry: Overview of the chemical composition of seawater, including dissolved gases, salts, and nutrients.
Biogeochemical Cycling: Study of the movement and transformation of elements and compounds within the oceanic ecosystem.
Ocean Acidification: The process by which increases in atmospheric carbon dioxide results in the lowering pH of the ocean.
Oceanography Instrumentation: Understanding the various devices and sensors used to measure chemical and physical properties of seawater.
Marine Pollution: Examination of the negative impacts of human activities on the ocean environment, including oil spills, waste disposal, and plastics.
Carbon Cycle: The exchange of carbon between the ocean, atmosphere, and land.
Analytical Chemistry Techniques: Methodologies that are used for exploring the chemical composition of seawater, including inorganic and organic analysis.
Nutrient Dynamics: The cycling of critical elements, like nitrogen and phosphorus, within marine ecosystems.
Trace Metals: Understanding the behavior and cycling of heavy metals in seawater, including their toxicity to living organisms.
Microbial Ecology: Study of the function, diversity, and interactions of microorganisms in ocean environments.
Climate Change: Understanding the role of the ocean in the global climate system and the impacts of climate change on the oceanic ecosystem.
Sediment Geochemistry: Study of the chemical composition and reactivity of materials that accumulate on the seafloor.
Oceanic Carbon Sequestration: Techniques that can be used to remove carbon from the atmosphere and store it in the deep ocean.
Marine Biogeochemistry: An interdisciplinary field that studies the interaction of physical, chemical, and biological processes that shape the oceanic ecosystem.
Oceanic Circulation: Understanding the movement of water and its associated heat, energy, and matter, in the ocean's complex circulation system.
Coastal Oceanography: Examining the interaction between seawater and coastal environments, including the impact on ecosystems and human activities.
Dissolved Organic Matter: The molecular-level understanding of the organic matter that is transported and transformed in the oceanic environment.
Marine Carbonate Chemistry: Understanding the formation, dissolution, and preservation of calcium carbonate in the ocean.
Marine Geology: Study of the chemical and physical processes that lead to the formation of marine sediments and the shaping of the seafloor.
Ocean Ecosystem Dynamics: Understanding the complex interactions between different species in the marine environment, including predator-prey relationships and biogeochemical cycles.
Nutrient Biogeochemistry: It deals with the study of inorganic and organic nutrients like nitrogen, phosphorus, and carbon that support the growth of marine organisms. It also involves the study of the factors that affect the distribution of nutrients in the ocean and their cycling.
Trace Metal Biogeochemistry: It is the study of the distribution and cycling of trace elements like iron, zinc, and copper in seawater. These elements play a significant role in various physiological and ecological processes and their availability in the ocean often limits the growth and distribution of marine organisms.
Organic Geochemistry: It deals with the study of the chemical composition and properties of organic compounds like lipids, proteins, and carbohydrates in seawater. These compounds are produced by marine organisms and their degradation can have a significant impact on the marine ecosystem.
Sediment Biogeochemistry: It involves the study of the chemical composition and properties of ocean sediments and how they respond to changes in the ocean environment. This research area includes the study of biogeochemical cycles of nutrients and trace elements in sediments and their interaction with the atmosphere and ocean.
Ocean Acidification: It is the study of the impacts of increased carbon dioxide levels in the atmosphere on the chemistry of seawater. The increased levels of carbon dioxide in the atmosphere lead to increased acidity in seawater, which can have significant impacts on the marine ecosystem.
Marine Pollution: It deals with the study of the effects of pollutants like heavy metals, plastics, and hydrocarbons on the marine environment. This research area includes the study of the sources of pollutants, their distribution, and their impacts on marine organisms and ecosystems.
Isotope Biogeochemistry: It includes the study of the isotopic composition of various elements in seawater and marine organisms. The isotopic composition can provide insights into the biogeochemical processes that control the cycling of nutrients and trace elements in the ocean.
"Marine life has adapted to the chemistries unique to earth's oceans, and marine ecosystems are sensitive to changes in ocean chemistry."
