New equipment was purchased in the Spring of 2002 with the intent of providing state-of-the-art positioning information for features that were unsurveyed, traditionally-surveyed, or surveyed with older GPS equipment.</p></kbsml_text>LTERKBSKellogg Biological StationHickory CornersMichiganGreat LakesKellogg Biological StationData Manager
