The Holocene Temperature Conundrum
The Holocene is the current geological era, which started 11,700 years before present and is divided into three stages: 8, 200, and 4,200 years before present. The early stage is the Greenlandian, the middle stage is the Northgrippian, and the late stage is the Meghalayan. According to proxy-based climate reconstructions, the global mean surface temperature during the Greenlandian and the Northgrippain was warmer than the Pre-industrial (PI). How…
Radiocarbon and Uranium Profiles in Marine Gastropods Around the Japanese Archipelago
In this study, we investigate the distribution of radiocarbon and uranium in the calcified opercula of Turbo sp. collected from Ryukyu region and Chiba, Japan, to explore the potential of U/Th dating using mollusks collected from the Japanese archipelago. We acquired high-resolution radiocarbon and uranium concentration measurements using single-stage accelerator mass spectrometry and laser ablation−inductively coupled plasma−mass spectrometry. O…
Insight into Western Pacific Circulation from South China Sea Coral Skeletal Radiocarbon
The trajectory of the Kuroshio, the western boundary current in the north Pacific, influences regional climate. It intrudes into the South China Sea (SCS) through the Luzon Strait, resulting in the exchange of water, nutrients, heat, and salt between the Pacific and SCS. It has been reported that the trajectory of the Kuroshio has varied with decadal climate changes. However, there has been no report of an observation-based estimate of the variat…
Dissolved inorganic Radiocarbon content of the Western Coral sea
The South Pacific Ocean contributes to the global carbon cycle by exchanging CO 2 between the atmosphere and intermediate to deep water masses. The path of the Antarctic Intermediate Water (AAIW) in the South Pacific gyre has been inferred from salinity, oxygen, and nutrient measurements, but radiocarbon ( 14 C) measurements—a direct tracer of the carbon cycle—remain sparse. Here, we present the first radiocarbon profiles in the western Coral Sea…
