WEATHER CONDITIONS

Season phenology:

Weather conditions:

Observers in the Colville River Delta and Prudhoe Bay areas reported spring as 4-7 days later than 1998 which was reported early across the breadth of the coastal plain.

Date of final loss of snow:

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Abundant sea ice and in lakes, fresh-water ice was present until 1 July. In larger coastal lakes such as Teshekpuk Lake, ice cover was more extensive and likely persisted much longer.
 

Rodent dynamics:

Snowy Owls were rare to absent east of the Meade River suggesting lemming abundance may have been a local phenomena near Barrow. Limited investigation in the Prudhoe Bay area suggested very low small mammal populations.
