“…Thus, the δ 18 O aragonite records of C. iejimensis provide unique data for reconstructing Holocene oceanographic changes in the East China Sea. However, Yamamoto et al (2009b) found no systematic ontogenetic variations in the δ 18 O aragonite values of empty shells from surface sediment within Daidokutsu cave, which is inconsistent with previous interpretations (Kitamura et al, 2007b;Yamamoto et al, 2008).…”

“…Kitamura et al (2007b) measured the δ 18 O aragonite values of 30 empty and whole shells of C. iejimensis picked from the N1 mm fractions of surface sediments (uppermost 5 cm of sediment, representing the past 250 years) within Daidokutsu cave, and obtained a statistically significant correlation between shell size and δ 18 O aragonite (r = − 0.55, p b 0.01). Yamamoto et al (2008) added to this dataset the δ 18 O aragonite values of 17 empty and whole shells collected from surface sediments within Daidokutsu cave (n = 47, r = − 0.37, p b 0.05) (Fig. 5a), and calculated the following relationship:…”

“…To this end, Kitamura et al (2007b) and Yamamoto et al (2008) measured the δ 18 O aragonite values of empty (dead) and whole shells of the cavernicolous micro-bivalve C. iejimensis, which lives in surface sediment within the submarine cave Daidokutsu (meaning large cave in Japanese; 29 m water depth; 26°43′N, 127°44′E) of Okinawa, Japan (Fig. 2).…”

a b s t r a c tThe micro-bivalve Carditella iejimensis inhabits the sediment surface within submarine caves at Ie Island, Okinawa, Japan. A comparison of the δ 18 O values (δ 18 O aragonite ) of empty and living shells indicates that the shell is formed over several seasons, and that the main cause of mortality is low water temperature. According to this hypothesis, it is likely that the shells with heaviest δ 18 O aragonite values (− 0.4‰) among the recent dataset formed under or close to the lower limit of growth temperature for the species. Assuming an unchanging temperature tolerance of the species during the Holocene, samples with δ 18 O aragonite values heavier than − 0.4‰ indicate unusually low temperatures and enrichment of δ 18 O of sea water (δ 18 O seawater ). The δ 18 O aragonite record of C. iejimensis from sediment cores recovered from Daidokutsu cave shows no clear long-term trend in sea surface temperature or δ 18 O seawater in the East China Sea during the past 7000 years, and indicates anomalously cool and dry events (enrichment in δ 18 O seawater ) at around 6300 and 5550 cal. years BP. These events may have been related to changes in the activity of the East Asian monsoon, related in turn to weakening solar activity. In contrast, these anomalies appear to be obscured during the last 1000 years, including a weak Asian summer monsoon event during the Little Ice Age, thereby indicating that the mode of the East China Sea climatic and hydrologic response to decadal-to centennial-scale variability in the intensity of East Asian monsoon has varied over the past 7000 years.

“…A number of workers have recently used archival materials from submarine caves to reconstruct environmental changes during the late Quaternary (Antonioli et al, 2001;Kitamura et al, 2007, Yamamoto et al, 2008, 2009a. For example, oxygen-isotopic compositions of coralline sponges and micro-bivalves from submarine caves have been studied as proxies for palaeotemperature (Böhm et al, 2000;Haase-Schramm et al, 2003;Yamamoto et al, 2008Yamamoto et al, , 2009bYamamoto et al, , 2010Kitamura et al, 2013).…”

We examined the spatial distributions and 14 C ages of sessile marine organisms in the submarine cave Ginama at Okinawa, Japan. The cave is the northernmost and only known submarine cave with an air chamber in the northwestern Pacific region. The upper limit of living individuals of the coralline sponges Acanthocaetetes wellsi and the bivalve Pycnodonte taniguchii in the cave is located at a depth of approximately 10 m relative to the surface of the pool in the cave. Low temperatures and low salinities prevent these organisms from colonizing water depths shallower than 10 m. On the other hand, the upper limit of fossil individuals, dated between 5117 and 387 cal yr BP, is at a depth of 2.5 m, implying that at present the influence of fresh water on the cave pool is stronger than it has been at other times in the past 5000 years. This increase in the flux of fresh water may be explained by continuous cavern-forming activities such as dissolution.

Low‐frequency storminess signal at Bermuda linked to cooling events in the North Atlantic region

North Atlantic climate archives provide evidence for increased storm activity during the Little Ice Age (150 to 600 calibrated years (cal years) B.P.) and centered at 1700 and 3000 cal years B.P., typically in centennial-scale sedimentary records. Meteorological (tropical versus extratropical storms) and climate forcings of this signal remain poorly understood, although variability in the North Atlantic Oscillation (NAO) or Atlantic Meridional Overturning Circulation (AMOC) are frequently hypothesized to be involved. Here we present records of late Holocene storminess and coastal temperature change from a Bermudian submarine cave that is hydrographically circulated with the coastal ocean. Thermal variability in the cave is documented by stable oxygen isotope values of cave benthic foraminifera, which document a close linkage between regional temperature change and NAO phasing during the late Holocene. However, erosion of terrestrial sediment into the submarine cave provides a "storminess signal" that correlates with higher-latitude storminess archives and broader North Atlantic cooling events. Understanding the driver of this storminess signal will require higher-resolution storm records to disentangle the contribution of tropical versus extratropical cyclones and a better understanding of cyclone activity during hemispheric cooling periods. Most importantly, however, the signal in Bermuda appears more closely correlated with proxy-based evidence for subtle AMOC reductions than NAO phasing.
