  1. Further Advancements to Iron FertilizationBy Jonathan TamLook Over, Jim 

  2. Key Points of LOHAFEX • Examine CO2 and N2O • Examine effects of Iron Fertilization on Krill • Examine Environmental Effects of Iron Fertilization • GOOD FUTURE STUDIES FOR US

  3. LOHAFEX – Stats • Experiment Ran in January 2009 • http://www.etcgroup.org/upload/publication/712/01/nretc_lohafexupdate13jan09_final.pdf • http://www.awi.de/fileadmin/user_upload/News/Press_Releases/2009/1._Quartal/LOHAFEX_22_01_09_Handout_engl.pdf • http://www.eurekalert.org/pub_releases/2009-01/haog-lai011309.php • http://www.nio.org/projects/narvekar/Lohafex_news_12_01_09.pdf • LOHAFEX is the first of a new generation of iron fertilization experiments in the field of ocean research to ameliorate the dangerous effects of ongoing climate change.

  4. LOHAFEX – Data • Collected Data in the form of Nitrous Oxide not Carbon Dioxide • http://www.awi.de/fileadmin/user_upload/News/Selected_News/2009/LOHAFEX/20090209_Data%20report%203.pdf • We Could Possibly Add More Organisms • http://www.awi.de/fileadmin/user_upload/News/Selected_News/2009/LOHAFEX/20090127_Phytoplankton.pdf • List of Several Diatoms/Dinoflagellates used in previous experimentation on Page 4 • Krill has been suggested in feeding the Antarctic region from dying species • Died about 80% in past decade

  5. Addition of Phosphorus • Acts as a Co-Factor to Iron • Currently Studied post-Iron Fertilization • http://www.sciencemag.org/cgi/content/abstract/304/5669/414 • http://www.nature.com/nature/journal/v429/n6989/abs/nature02550.html • http://www.ifm-geomar.de/fileadmin/ifm-geomar/allgemein/avillwock/jb_pdfs/chapter3_8_nitrogen.pdf • http://www.biogeosciences.net/4/455/2007/bg-4-455-2007.pdf

  6. Addition of Silica • http://disc.gsfc.nasa.gov/oceancolor/scifocus/oceanColor/iron_limits.shtml • Necessary in forming outer shell layers of most species of Diatoms • “Diatoms form shells out of silica, and these shells come in an enormous variety of shapes and sizes. An example of a few different diatoms is shown below.”

  7. Change in Sea Water • Obtain Sea Water from an HNLC region • Would help in re-enacting Iron Fertilization Effect • Addition of “OTHER” nutrients would be as well • http://www.soest.hawaii.edu/oceanography/courses/OCN626/2008_OCN%20626/HNLC%20regions%20lecture_2008.pdf • Extremely Difficult 
