•» Lombard et al. (2006) opined that recent investigations based on new
ocean temperature data sets indicate that thermal expansion only explains part (about 0.4 mm / yr) of the 1.8 mm / yr observed sea level rise of the past few decades.
Near - global
ocean temperature data for the last 50 years have been recently made available, allowing the first observationally based estimate of the thermal expansion contribution to sea level rise in past decades.
In fact, «Atlantic
Ocean temperature data shows that this is just the latest manifestation of a long - running hurricane cycle that dates back to at least 1870,» said Landsea.»
Marine scientists from Stony Brook University in New York state report in the Proceedings of the National Academy of Sciences that they looked
at ocean temperature data and the growth of two of the most toxic algae in the North Atlantic and North Pacific oceans.
He currently works seasonally as a commercial lobster fisherman and periodically for Scripps Institution of Oceanography
collecting ocean temperature data during crossings of the Pacific Ocean.
I obviously don't have access to the same high - resolution data, but, if the SH was not warming and did not experience warming at the same time, then why do the Antarctic ice cores show the warming pulse in sync with the NH warming if the ice cores do not collect long
range ocean temperature data?
The quarrel began with a paper by NOAA scientists published 5 June in Science that revised historical atmosphere and
ocean temperature data records found to have been poorly calibrated.
A team of scientists led by Dr. Christopher Gobler, marine science professor in the School of Marine and Atmospheric Sciences at Stony Brook University, used high
resolution ocean temperature data along with the growth response of two of the most toxic algae in the North Atlantic and North Pacific Oceans called Alexandrium and Dinophysis.
At various points along the cores, the researchers measured Ca and Sr levels and matched them to
known ocean temperature data for the corresponding time periods.
Ocean temperature data prior to the 1980s had been taken from ship - based temperature measurements, and is now obtained via satellite measurements.
In the past, as PopSci previously reported,
most ocean temperature data was taken by ships which pulled water into their engine rooms — rooms warmer than the ocean outside, making ocean temperature recordings slightly higher.
For example in the technical summary, it says:» The global combined land and
ocean temperature data show an increase of about 0.8 °C over the period 1901 — 2010 and about 0.5 °C over the period 1979 — 2010.
that they looked
at ocean temperature data and the growth of two of the most toxic algae in the North Atlantic and North Pacific oceans.
A few years ago the New England fishing fleets were in despair because the fish were nowhere to be found; a biologist, who had been making a laboratory study of the temperature of fishes» stomachs, combined his data with
some ocean temperature data and correctly suggested where the missing creatures might be found.
The consistency between these two data sets gives confidence in
the ocean temperature data set used for estimating depth - integrated heat content, and supports the trends in SST reported in Chapter 3.
When I reviewed
the ocean temperature data sets back in 2003 through 2005 that appeared to have been data taken in the N. Atlantic above the 30th parallel, with an indication of cooling in the 2300 to 1700 meter range.
To what extent did internal discussions occur regarding some of the more questionable choices made in adjusting
the ocean temperature data?
The consistency between these two data sets gives confidence in
the ocean temperature data set used for estimating depth - integrated heat content, and supports the trends in SST reported in Chapter 3.
Other data sources were investigated, including the new Berkeley land -
ocean temperature data, the MERRA weather model reanalysis, and satellite radiometer datasets from AIRS and AVHRR.
And
ocean temperature data can't be used instead since this is not available for the Arctic Ocean.

ocean temperature data (created by tamino)
