The atmosphere is definitely informal, and old clothing is the norm. If you plan to visit field sites, you might want to bring along rubber boots or be prepared to get your feet wet. Rain gear is also recommended unless you like to get wet, although some summers have been quite dry. The climate of the ELA is continental, with hot summers and cold winters. Precipitation is light to moderate, with much of the rain coming in sudden thunderstorms.
Evenings are often cool, however.
Anyone planning to do research should check in advance to determine what equipment is available on site. In general, field transportation and support are provided, although specialized equipment may have to be brought with you. Laboratory space will normally be provided, but specialized instruments should be brought with you unless you have arranged in advance to use instruments on site. The field station stocks a limited quantity of general supplies, but these are intended only for emergency use. The ELA field station operates as a small research community.
