Climate change leave footprint in the he ancient evolution of the earth, which support the climate reconstruction. Greenhouse gas emission after the industrial revolution, Global warming and ocean acidification are affecting the biogeochemical processes and marine ecosystem. Hence, we develop the cutting-edge technology, explore the fundamental scientific questions, and focus on but not limited on the following research areas:

- Paleoclimate/Evolution of Modern Ocean

- Paleoclimate reconstruction from ice cores to study the productivity

- Ocean circulation in the past from corals and sediments

- Carbon Cycle and Biogeochemistry

- Air-sea gas exchange to estimate oceanic uptake and release of greenhouse gases

- Biological pump in carbon exportation and physical regulation

- Ocean acidification and influences on marine ecosystem

Thus, we are developing the automatic operation of vacuum system and incorporate with isoptopic ratio mass spect (Thermo Mat 253 and delta V), thus we can meet the challenge in high precision analysis for tiny amount of gasses and gas composition in ice core. We developed multiple sets of underway system in high frequency and high precision analysis for special and temporal changes in the ocean carbon cycles. For example, we deploy the quadruple mass spectrometer to analyze O2/Ar continues changes in order to estimate net community production. Based on cavity ringdown spectrometer, the dissolved inorganic carbon could be analyzed automatically and continuously, in return, acidification and other carbonate parameters could be calculated when to couple DIC with pH underway analysis. Different phytoplankton community exhibit various responses to excitation/emission in different wavelength, we took this advantages to estimate community effect in carbon fixation and electron transportation in synthetic observation that comparable to other underway estimates.
