Common techniques for water sampling include using Niskin bottles for discrete depth sampling and CTD rosettes for profiling. After sampling, water is analyzed for salinity, temperature, and chemical content using spectrophotometry and chromatography. These methods help determine the health of marine ecosystems.

Seafloor mapping primarily uses methods such as multibeam sonar, which sends sound waves to measure seafloor depth and features, and satellite altimetry, which measures sea surface height to infer seafloor topography. Challenges include high operational costs and complex data processing, as well as difficulties caused by water depth and turbidity affecting sonar effectiveness.

Plankton are crucial because they form the foundation of the ocean food web, providing energy for larger marine creatures. They also produce a significant amount of the Earth's oxygen through photosynthesis. Researchers study plankton using water sampling techniques and microscopic analysis to understand environmental conditions and changes in marine ecosystems.

Ocean acidification is caused primarily by the absorption of atmospheric CO2 into ocean waters, which lowers the pH. This leads to detrimental effects on marine organisms, particularly shellfish and coral reefs. We can measure this phenomenon by using pH sensors and conducting water samples to analyze carbonic acid levels.

I study hydrodynamic processes by combining field measurements with numerical simulations, using tools like Delft3D and ROMS. For example, I've modeled tidal currents in estuarine environments to understand sediment transport dynamics.
