(except to submit it by the due date shown on the calendar). This exercise will be graded automatically. 20 / 20 pts Question 1 Type "Alley RB" into the author space on the Web of Science. You will find lots of pages of refereed scientific literature that Dr. Alley has worked on. What was he publishing on in 1987? (Hint: the older ones are near the back, so use the “page” box near the top in the center to go there.) Coordination numbers, grain growth in ice, and till compaction. Deforming­bed origin of southern Laurentide till sheets, and changes in the West Antarctic ice sheet. Deposition and diagenesis of strata in polar firn, and fabrics in polar ice sheets.
1/29/2018 Exercise #1: Scientific Literature: GEOSC 10: Spring 2018, Geology of the National Parks, merged Water­pressure coupling of sliding and bed deformation, and sedimentation beneath ice shelves. Till beneath ice streams, and firn densification. Correct! Correct! The Web of Science lists 7 papers that Dr. Alley helped write and that have 1987 publication dates. Four concern mud (till) beneath Antarctic ice streams, and particularly beneath one called Ice Stream B. One is on the transformation of old snow (called firn) to ice, and the others are on processes in ice that cause crystals (or grains) to grow and that control the rate of ice deformation (rheology). Dr. Alley published on many other things in other years, but these were the 1987 contributions. Eventually, these help us understand how ice sheets work, and whether the ice will fall in the ocean and flood the coasts. 20 / 20 pts Question 2 Scientists collaborate a lot. The Web of Science tells you who all the coauthors are. Search on Dr. A (Type “Anandakrishnan S” into the author box of the search page). Notice that many of the entries list a few authors followed by “et al.” (which stands for “et alia” and means “and others” in Latin). If you click on the blue title, you’ll see a list of all of the authors. So, who was Dr. A co­authoring with in 1997? Correct! Correct!
4/8 T.K. Dupont and J.P. Winberry, among others. K.M. Cuffey, and J.M. Bolzan, among others.
1/29/2018 Exercise #1: Scientific Literature: GEOSC 10: Spring 2018, Geology of the National Parks, merged 5/8 Dr. Anandakrishnan collaborated and coauthored with all of the people listed, and has worked with many other people; the key is finding the 1997 list. Dr. Anandakrishnan’s 1997 colleagues worked at Los Alamos laboratory when he was there, addressing the key question of identifying illegal atomic­bomb testing by rogue nations. Blasting in surface coal mines can involve huge explosions, and Dr. Anandakrishnan helped show how to distinguish between these legal explosions and illegal ones. 20 / 20 pts
