4214. Lake Michigan #20 net, vertical tow 30m to surface 4443.8N, 8715.9W 5 April 1992.
4215. Lake Michigan #20 net, vertical tow. Deep water station between Grand Haven and South Haven. Samples taken for RV Laurentian Open House exhibit 2-3 June 1992. Sample was untreated and allowed to 'rot' naturally to preserve the frustule structure but loose the organic coating Slide 4125a was ashed on a hotplate. Slide 4215b was air dried and mounted without ashing.
