Answer: A - P.M. Grootes, K.M. Cuffey, and J.M. Bolzan, among others.
Explanation: Dr. Anandakrishnan collaborated and coauthored with all of the people listed above and has worked with many other people.
During the year 1994, Dr. Sridhar Anandakrishnan collaborated with Kurt M Cuffey, Richard B Alley, Pieter M Grootes and John M Bolzan on the topic 'Calibration of the δ18O isotopic paleothermometer for central Greenland, using borehole temperatures'
They calibrated the δ 18O paleo-thermometer for central Greenland using borehole temperatures, a thermal model forced by a measured δ 18O record and a formal inverse technique. The calibration is determined mostly by temperature fluctuations of the last several centuries, including the Little Ice Age.
Results are generally insensitive to model variables, including initial condition, basal boundary condition, parameterization of snow thermal properties, ice thickness and likely errors in temperature and isotope measurements. Results of this borehole calibration also seem to be in agreement with modern spatial gradients of δ 18O and temperature.
They suggest that calibrations of isotopic paleothermometers using borehole temperatures are a useful paleoclimate tool because they are independent of spatial gradients and include the effects of prehistoric temperatures.

The ocean floor or seabed can be divided into three major regions: the continental margins, abyssal plains, and mid-ocean ridges.
<span>As of 2016, farm and ranch families made up only two percent of the total US population. The amount of farmer and ranching families has declined at a fast pace since it's peak in 1935. In the last twenty years most of the decline can be blamed on how little farmers and ranchers make from the food they grow or raise. Farmers and ranchers only receive, on average, sixteen cents for every dollar that is spent on food in both grocery stores, down from about thirty-one cents for every dollar in the 1980's.</span>
