Seamounts are mountains that rise from the seafloor. The technical geological definition of a seamount is a steep-sided feature with greater than 1000 m of relief compared to the surrounding sea botto...
Deep-sea corals are solitary and colonial suspension-feeding cnidarians commonly associated with seamounts around the world. They are important components of seamount ecology, providing food and refug...

Offsets from isotopic equilibrium in biogenic carbonates have complicated paleoclimate reconstructions for decades. A new archive of climate, deep-sea corals, is used to evaluate the calcification pro...
Deep-sea corals are a promising new archive of paleoclimate. Coupled radiocarbon and U-series dates allow 14C to be used as a tracer of ocean circulation rate in the same manner as it is used in the m...
230Th, 232Th, 234U and 238U compositions of several deep-sea solitary corals, mainly the species Desmophyllum cristagalli, were determined by thermal ionization mass spectrometry (TIMS). It is possibl...
