  9. ? Terrestrial Support = ALLOCHTHONY What carbon supports lake food webs…. In Lake Support = AUTOCHTHONY Dissolved CO2 CO2 Stable isotopes can label autochthonous production

  10. June 7:Sure was hot today June8: Maybe I’ll cruise out to pelagic, see what Fox is eating June 9: Got away from that big silver boat again last night, that makes it 3 weeks in a row Challenges of studying fish.. ….can’t see where they go ….what temperature do they prefer? ….what stream did they come from? ….what were they eating yesterday or last month?

  11. Need a record of what a fish does or experiences... ….the OTOLITH COMPOSITION Calcium Carbonate (Aragonite) And a Protein Matrix FUNCTIONS Hearing/Vibrations Orientation (Frustrating fisheries students) http://perso.club-internet.fr/jflhomme/otolithes/desc_otolithe.html

  12. δ18O Water Temperature Bob Jones, Old Dominion University What’s so unique about them? Accrete “proportional” to fish growth Remain chemically and isotopically inert Major Elements calcium, oxygen, carbon Minor and Trace Elements sodium, strontium, sulfur, nitrogen, barium, iron…..plus at least 2 dozen more ? Otolith Carbon ? ? ? WATER FOOD

  13. Micro mill 30um Ion Probe 3-4um Cameca IMS-1280 If we could just measure a small enough sample…..enter in Dr. Valley and WISC-SIMS
