Sediment iron and phosphorus species and fluxes at Haima methane seeps
Aug 6, 2025 - Biogeochemistry of deep-sea methane seeps
LI, Jiying; LIN, Yuxuan, 2025, "Sediment iron and phosphorus species and fluxes at Haima methane seeps", https://doi.org/10.14711/dataset/VOGU6C, DataSpace@HKUST, V3, UNF:6:sqa3PMckjyftBg7X8/jpLA== [fileUNF]
We characterize the geochemistry of the sediments in the deep-sea methane seeps located in the continental slope of the northern South China Sea, the Haima cold seeps (1300–1500 m) and quantify the effluxes of dissolved iron and phosphate from the sediments.
Sediment nitrogen fluxes and rates in the Pearl River Estuary region
Apr 14, 2025 - Sediment biogeochemistry in the Pearl River Estuary Region: carbon, nitrogen, and phosphorus cycling
LI, Jiying; SUN, Jing; Yu, Liuqian, 2024, "Sediment nitrogen fluxes and rates in the Pearl River Estuary region", https://doi.org/10.14711/dataset/XMTKWW, DataSpace@HKUST, V3, UNF:6:vmin2pjYEElVJqGcQIuJxA== [fileUNF]
We collected water and sediment samples from the Pearl River Estuary and its adjacent coastal shelf. We measured dissolved oxygen, ammonium, and nitrate in the porewaters and particulate organic carbon and nitrogen. We estimate the sediment oxygen uptake using whole core incubati...
Sediment phosphorus and iron speciation and fluxes in the Pearl River Estuary region
Jan 9, 2025 - Sediment biogeochemistry in the Pearl River Estuary Region: carbon, nitrogen, and phosphorus cycling
LI, Jiying; SUN, Jing, 2025, "Sediment phosphorus and iron speciation and fluxes in the Pearl River Estuary region", https://doi.org/10.14711/dataset/YREFNP, DataSpace@HKUST, V1, UNF:6:XzaJv4gjhOou9gWfE1HFEA== [fileUNF]
We measured the vertical distributions of dissolved and solid phosphorus (P) and iron (Fe) species in the sediments of the Pearl River Estuary and the adjacent shelf, calculate the effluxes of phosphate across the sediment water interface, and estimate the recycling efficiency of...
Polyphosphate extraction and quantification in environmental planktonic samples using a fluorescence dye JC-D7, method assessment
May 6, 2024 - Polyphosphate in aquatic environments
LI, Jiying, 2024, "Polyphosphate extraction and quantification in environmental planktonic samples using a fluorescence dye JC-D7, method assessment", https://doi.org/10.14711/dataset/A1BO6O, DataSpace@HKUST, V1, UNF:6:vZExePw2W4wTUE6K2UiVaw== [fileUNF]
We develop and evaluate a method for quantifying polyP in environmental planktonic samples. This dataset includes two data files. The first file (table) includes the responses of polyP-JC-D7 fluorescence signal (excitation 405 nm, emission 535 nm) under a range of polyP concentra...
Sediment oxygen uptake and hypoxia in the Pearl River Estuary Region
Mar 11, 2024 - Sediment biogeochemistry in the Pearl River Estuary Region: carbon, nitrogen, and phosphorus cycling
LI, Jiying; SUN, Jing; YU, Liuqian; GAN, Jianping; YANG, Xingyu, 2024, "Sediment oxygen uptake and hypoxia in the Pearl River Estuary Region", https://doi.org/10.14711/dataset/KCLUQW, DataSpace@HKUST, V1, UNF:6:CkRCkLArRYmQqn66DS8NQw== [fileUNF]
The dataset includes sediment oxygen uptake, sediment oxygen profiles, sediment oxygen penetration depth, water column CTD profiles (temperature, salinity, sigma density, oxygen, and chlorophyll a), and buoyance frequency (N2) from the Pearl River Estuary and adjacent coastal she...
