The seasonality of sea surface temperatures (SST) estimated from the alkenone-[Formula:
see text] index has been a debated issue since the development of the proxy. Using a …

The alkenone‐based U proxy is a cornerstone of paleoclimatology, providing insight into the
temperature history of the Earth's surface ocean. Although the relationship between U and …

In this paper, we compile the current surface seawater C37 alkenone unsaturation (UK′ 37)
measurements (n= 629,− 1 to 30° C temperature range) to derive a global, field‐based …

Being able to decipher paleo sea surface temperatures for warm oceanic waters is of the
utmost importance to further evaluate the role of the tropics in global climate change. The …

The Mg/Ca ratio has been measured in two surface‐dwelling species of planktonic
foraminifera, Globigerinoides ruber and Globigerina bulloides, from biweekly sediment trap …

Centennial‐scale records of sea‐surface temperature and opal composition spanning the
Last Glacial Maximum and Termination 1 (circa 25–6 ka) are presented here from Guaymas …

The Mediterranean Sea is at the transition between temperate and tropical air masses and
as such of importance for studying climate change. The Gulf of Taranto and adjacent SW …

We investigated the characteristics of the alkenones produced by a bloom of Emiliania
huxleyi in the eastern Bering Sea in 2000. Alkenones were detected in surface waters …

I review the status of alkenone unsaturation parameters as proxies for growth temperature
and the potential for pCO2 estimates using the carbon isotopic composition of alkenones …

Geochemical sea surface temperature (SST) proxies such as the magnesium to calcium
ratio (Mg/Ca) in foraminifera and the alkenone unsaturation index (UK′ 37) are becoming …
