A 420-year history of strontium/calcium, uranium/calcium, and oxygen isotope ratios in eight coral cores from the Great Barrier Reef, Australia, indicates that sea surface temperature and salinity were higher in the 18th century than in the 20th century. An abrupt freshening after 1870 occurred simultaneously throughout the southwestern Pacific, coinciding with cooling tropical temperatures. Higher salinities between 1565 and 1870 are best explained by a combination of advection and wind… 
Climate and hydrographic variability in the Indo‐Pacific Warm Pool during the last millennium
Planktonic foraminiferal Mg/Ca and δ18O derived sea surface temperature and salinity records from the Makassar Strait, Indonesia, show a long‐term cooling and freshening trend, as well as

Reconstructions of ocean temperatures prior to the industrial era serve to constrain natural climate variability on decadal to centennial timescales, yet relatively few such observations are
Decadal-Scale SST and Salinity Variations in the Central Tropical Pacific: Signatures of Natural and Anthropogenic Climate Change
Accurate projections of future temperature and precipitation patterns in many regions of the world depend on quantifying anthropogenic signatures in tropical Pacific climate against its rich
Rapid reorganization in ocean biogeochemistry off Peru towards the end of the Little Ice Age
Abstract. Climate and ocean ecosystem variability has been well recognized during the twentieth century but it is unclear if modern ocean biogeochemistry is susceptible to the large, abrupt shifts

Enhancement of coastal upwelling and interdecadal ENSO‐like variability in the Peru‐Chile Current since late 19th century
Secular trends in coastal upwelling proxies from a sediment record at 23°S encompassing 250 years reveal two distinct stages separated by a transition period between AD 1820 and 1878. Persistent

The Little Ice Age as Recorded in the Stratigraphy of the Tropical Quelccaya Ice Cap
TLDR
The analyses of two ice cores from a southern tropical ice cap provide a record of climatic conditions over 1000 years for a region where other proxy records are nearly absent and confirms the worldwide character of the Little Ice Age.

Decadal sea surface temperature variability in the subtropical South Pacific from 1726 to 1997 A.D.
TLDR
Calibration with monthly sea surface temperature (SST) from satellite and ship measurements made in a grid measuring 1 degrees by 1 degrees over the period from 1981 to 1997 indicates that this Sr/Ca record is an excellent proxy for SST, and hemispheric symmetry suggests that tropical forcing may be an important factor in at least some of the decadal variability observed in the Pacific Ocean.
