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.
Yes it is true.
Hope this helps
It's becasue human populations are concentrated in areas that are lacking proper resources.
Answer:
<u>False, Not necessarily</u>
Explanation:
- According to the question,Kerneland suffers from a chronic scarcity of its staple grain, and corns which are agricultural products don't mean that a country is not self-sufficient in itself.
- Since Kernaland faces this scarcity it can import the same products from other countries to get rid of this problem which maintaining a balance of trade it can export what it specializes with.
- Developed countries have had similar problems of food scarcity in the earlier periods, but have overcome this. Blaming developing countries from the lack of food supplies is not a good way of understanding the economy, as many nations that are now developed or food sufficient had to import more of agricultural produce example is landlocked countries.
