“…For most of the cooling months the contribution to pCO 2 change resulting from seawater temperature change (%Dtemp) was greater than that driven by other factors. The pronounced seasonal temperature effect on pCO 2 appeared to be ubiquitous in the coastal waters around Korea (Lee et al, 2022). However, the contribution of temperature change became smaller than the biological contribution (%Dbio) in the latter growing months, as the macroalgal growth remained strong.…”

Photosynthetic organisms shift the dynamics of surface pCO2 driven by the sea surface temperature change (thermodynamic driver) by assimilating inorganic C from seawater. Here we measured net C uptake in a macroalgal habitat of coastal Korea for two years (2019-2020) and found that the macroalgal habitat contributed 5.8 g C m−2 month−1 of the net C uptake during the growing period (the cooling period, September−May). This massive C uptake changed the thermodynamics-driven seasonal dynamics such that the air−sea equilibrium of pCO2 was pushed into disequilibrium. The surface pCO2 dynamics during the cooling period was mostly influenced by the seasonal decrease in temperature and the proliferation of macroalgae, while the dynamics during the warming period (the stagnant period, June−August) closely followed that predicted based solely on the change in sea surface temperature (thermodynamic driver). In contrast to the phytoplankton-dominated off-shore waters (where phytoplankton populations are large in spring and summer), the impact of coastal macroalgae on surface pCO2 dynamics was most pronounced during the cooling period, when the magnitude of pCO2 change was as much as twice that resulting from temperature change. Our study shows that the distinctive features of the macroalgal habitat—in particular the seasonal temperature extremes (~18°C difference), the active macroalgal metabolism, and anthropogenic nutrient inputs—collectively influenced the seasonal decoupling of seawater and air pCO2 dynamics.

The Ieodo Ocean Research Station (IORS) has been a critical site for collecting oceanic and atmospheric data over 19 years (2005-2023). This study analyzes key parameters including tide, wave, water temperature, salinity, wind, air temperature, etc. While these datasets have provided valuable insights into regional climatic and oceanographic phenomena, significant incorrect data were identified, particularly in the records from 2015 to 2019. Issues such as overlapping data spanning multiple years, non-chronological ordering, and discrepancies in decimal precision were detected likely due to inadequate data handling during the adjustment process in programs like Excel. These errors, which persisted for years without detection or correction, highlight a lack of responsibility and verification among both government and private sector employees involved in data management. Given the substantial investment of government resources in the IORS, the continuous presence of incorrect data on official platforms raises concerns that extend beyond the responsible parties to the broader scientific and public communities. To prevent future occurrences, the study emphasized the need for stringent data management practices and ongoing accuracy in data handling, ensuring that the IORS continues to serve as a reliable resource for oceanographic research in Korea and globally.
