SMALL WORLD!  I HAVE KNOWN HELMY WEISSERT A LONG TIME THROUGH OUR MUTUAL
INTERESTS IN CRETACEROUS CARBONATES WHICH I'M USUALLY WORKING ON WITH MIKE
ARTHUR AND/OR LISA PRATT.  WEARING MY OTHER ISOTOPE HAT, HOLOCENE
LACUSTRINE CARBONATES, I HAVE KNOWN JUDY FOR MANY YEARS AND I WAS A GOOD
FRIEND (STILL AM) WITH KERRY KELTS SINCE HIS DSDP DAYS.  I AM PRESENTLY
RUNNING ISOTOPES ON OSTRACODS FROM MINNESOTA LAKES PICKED BY ANTJE SCHWALB,
WHOM YOU PROBABLY KNEW AT ETH.  WE JUST SENT A REVISED PAPER OFF THE JOUR.
OF PALEOLIMNOL.  THE WORKHORSE OF USGS LIGHT STABLE ISOTOPE LAB HERE IN
DENVER IS A NEW FINNIGAN 251 WITH A KIEL DEVICE.  WE'VE BEEN RUNNING SINGLE
OSTRACODES FOR ANTJE'S WORK AND 2-3 FORAMS FOR OUR MARINE CORES.  THE MAIN
ISOTOPE LAB IS RUN BY BOB RYE, BUT THE 251 AND KIEL DEVICE IS BEING RUN BY
JIM BURDETT WHO WAS A STUDENT OF MIKE ARTHUR'S AT RHODE ISLAND, THEN WENT
TO MICHIGAN TO RUN K.C. LOHMANN'S  LAB, AND CAME HERE ABOUT 2 YEARS AGO.
I'LL SEND YOU A CARE PACKAGE.
