Cladocera anal y sis
Eemian Inter gla cial
palaeolake de vel op ment
NE Po land - Opis:
- This pa per pres ents de vel op ment of the paleolake Starowlany ex ist ing in the Eemian Inter gla cial (MIS 5e) in north - east ern Po land. The lake his tory is based on Cladocera anal y sis. The paleolake Starowlany is lo cated in the cen tral part of the Sokó³ka Hills, ap prox i mately 9 km north of the town of Sokó³ka in the North Podlasie Low land. The sed i ments stud ied filled a south ern part of a tun nel val ley formed dur ing the Warta Gla ci ation. The cor ing was car ried out with a geo log i cal drill ing and con sti tuted a part of the frame work aimed at pre par ing the Sokó³ka sheet for the De tailed Geo - log i cal Map of Po land in scale 1:50 000. The core was 7 m long. Peaty silt, peats and or ganic silt were pres ent at the depth of 4.0–6.6 m, un der deluvial sands, tills and silt. Or ganic se ries was over lain by a clayey silt with no gla cial cover. Cladocera anal y sis was con ducted with 20 sam ples from a depth in ter val 6.6–4.1 m. Re mains of 17 spe cies of Cladocera were found, rep re sent ing the fam i lies: Chydoridae, Sididae and Bosminidae. A vast ma jor ity of them were the lit to ral spe cies. In the paleolake Starowlany four de vel op ment zones were dis tin guished that re flected changes as re gards tem per a ture, trophic lev els and changes of wa ter level in the lake. The paleolake ex isted from the early un til the mid dle Eemian. The high est wa ter level and the most fa vor able con di tions for zoo plank ton de vel op ment oc curred in zones SCZ I and II. The high est trophic level took place in SCZ III (mid dle Eemian). In the late Eemian the wa ter level dropped and the paleolake was trans formed into a wet land. At cer tain points, the higher wa ter level en abled ex is - tence of a few Cladocera spe cies. The rea sons for dis ap pear ance of the paleolake Starowlany in cluded a lo cal de crease in ground wa ter lev els as well as morphometric and geo log i cal char ac ter is tics of the lake.
