Spring 2009

A large contingency of the Aquatic Toxicology laboratory descended on La Crosse, WI for the occasion of the Midwest SETAC annual meeting there in March 2009. The group presented three posters and five oral presentation during the three-day meeting.

Spring 2009

Spring 2009 saw the third one-day spring retreat at Ney Nature Center near Maple Lake. In addition to students and faculty, we now included several furry creatures in the proceedings.

Spring 2007

The Aquatic Toxicology Laboratory returned to the Ney Nature Center for another spring retreat in 2007. In addition to talks being rehearsed for upcoming meetings, the students tested their skills capturing with the high-speed video camera behaviors of wild birds frequenting the feeders all around the facility.

Fall 2006

The Aquatic Toxicology laboratory returned to the shores of Lake Okoboji in fall 2006 for another memorable multi-day retreat with the largest number of participants to-date. In addition to frying multiple turkeys (!) and fish, experiments with fried pizza and vegetables were only partially successful. Although it was colder than in the previous year, heating scientific discussions assured the success of the endeavor.

Spring 2006

The first one-day spring retreat was held at the Ney Nature Center near Maple Lake, MN in spring of 2006. Several of the students attending used the occasion to present talks that were being prepared for the Midwest SETAC meeting that was held later that spring in St. Cloud, MN under the auspice of the St. Cloud State University Aquatic Toxicology Laboratory.

Fall 2005

The longest retreat to-date with 13 participants was convened for three days in Fall 2005 on the shores of Lake Okoboji in the facilities of the Iowa Lakeside Laboratory. The weather was great, the food was fantastic and much scientific discussions were held.

Fall 2003

The Aquatic Toxicology Laboratories second retreat, held in Fall 2003 brought us to another important body of water – the source of the Mississippi River in Lake Itasca State Park. With much nicer weather than at the first retreat, we spent much time outdoors and thoroughly enjoyed the facilities provided by the University of Minnesota.

Student Retreats

The Fall 2002 retreat was the first one for the Aquatic Toxicology Laboratory and was held on the shores of Mille Lacs. Despite the cold and the crashing waves, we succeeded in frying (and eating) a turkey, establishing a tradition we have repeated in several subsequent retreats
