Subaqueous soil sequence in marine waters of the Strunjan Bay

Repe, Blaž (author), Pavlin, Tina (author)

Soil research focuses mainly on soils on land, but the process of soil formation also takes place in shallow waters. Subaqueous soils form below the water surface, mainly on the bottom of shallow, stagnant waters such as bogs, swamps, lakes, and shoals in the sea. Three subaquatic soil profiles were investigated in the Strunjan Bay to study them in detail. The sites for the soil investigation were selected after observing the movement of seawater and thus its possible influence on subaquatic soils. All the so-ils studied are permanently and year-round under water. Therefore, all soil samples were collected under water using drainage pipes and by excavation. The samples were slowly drained in the pipes to prevent mixing of the material and to keep the horizons as intact as possible. Visual observations and standard analyses were carried out in the laboratory according to the identified horizons. During the investigation, we found that apart from water properties and movement, most soil-forming factors can be considered constant, so we investigated and presented a soil hydrosequence. According to the WRB classification, the subaqueous soils in the waters of the Strunjan Bay were divided into the reference groups Gleysols and Leptosols.

• Title: Genetsko zaporedje podvodnih prsti v Strunjanskem zalivu

Abstract

Raziskovanje prsti se v glavnem osredotoča predvsem na prsti na kopnem, vendar se pedogenetski procesi nastajanja prsti pojavljajo tudi v plitvih vodah. Podvodne prsti nastajajo pod vodno gladino, predvsem na dnu plitvih, stoječih voda, kot so barja, močvirja, jezera in morske plitvine. V Strunjanskem zalivu smo proučevali tri podvodne profile prsti z namenom, da bi jih podrobneje raziskali in predstavili. Lokacije za raziskavo prsti so bila izbrane glede na opazovanje gibanja morske vode in posledično njenega možnega vpliva na podvodne prsti. Vse proučevane prsti so stalno in vse leto pod vodo, zato so bili vsi vzorci tal zbrani pod vodo z drenažnimi cevmi in s pomočjo izkopa. Vzorce smo počasi izsušili v samih ceveh in s tem preprečili mešanje gradiva in ohranitev horizontov. V laboratoriju smo opravili vizualna opazovanja in standardne analize za vsakega od prepoznanih horizontov. Med raziskavo smo ugotovili, da lahko poleg lastnosti vode in njenega gibanja večino pedogenetskih dejavnikov smatramo za konstantne, zato smo proučili in predstavili pedogenetsko hidrosekvenco prsti. Podvodne prsti pod vodo Strunjanskega zaliva so bile po mednarodni WRB klasifikaciji prepoznane in uvrščene v referenčni skupini Gleysols in Leptosols.
