Anrikning og omsetning av metaller i innsjøer utsatt for veiavrenning, studert med paleolimnologiske metoder
Rishatt, Andrea (Master thesis, 2018)Ved hjelp av paleolimnologiske metoder kan man undersøke metallkonsentrasjonene for de ulike lag i en sedimentsøyle og hvordan konsentrasjonene har endret seg over tid. En uforstyrret sedimentsøyle som går langt tilbake i ... -
Biogeochemical cycling and retention of Fe in boreal lakes
Børseth, Therese Merete (Master thesis, 2022)An observed trend of increasing iron (Fe) concentrations in boreal freshwaters has been attributed to changes in the biogeochemical cycling of Fe. To better understand the drivers behind this trend, as well as any potential ... -
Distribution of metals and organic material along a Norwegian river - ocean transect
Kleven, Anniken (Master thesis, 2021)The distribution of metals in aquatic systems is crucial for bioavailability and toxicity. Metals are transported from catchment to oceans through rivers. During this transport, the properties of metals (e.g., charge, size, ... -
Drivers for phytoplankton community dominance of nuisance microalga Gonyostomum semen (Ehrenberg) Diesing in two South-Eastern Norwegian lakes : a paleolimnological approach
Sunde, Sunniva Eide (Master thesis, 2018)Gonyostomum semen (Ehr.) Diesing has during the last decades expanded its distribution and increasingly started to dominate phytoplankton communities in Northern Europe, and particularly in Scandinavia. Several studies ... -
Gonyostomum semen : en klimaflyktning? : utvikling av algens dominans i to innsjøer i Østfold : en paleolimnologisk studie
Pechinkina, Liudmila (Master thesis, 2018)Organismer tilpasses de miljøforholdene (abiotiske og biotiske faktorer) de lever under. Dette innebærer at en populasjons utbredelse og størrelse blir begrenset av disse faktorene. En art med gode tilpasninger har bedre ... -
Rainfall-runoff modelling with high temporal resolution on the arable catchment Skuterud : assessing the performance of the Distance Distribution Dynamics model
Stavang, Anne Ellekjær (Master thesis, 2019)Runoff from arable land is recognised as the main reason for water degradation, eutrophication and reduced water quality. The aim of the study is to model runoff on a 1h temporal resolution from an arable catchment using ... -
Test af fluorometer i en turbid og humøs sø : kan et in situ fluorometer erstatte laboratoriemålinger af klorofyl a?
Reinemo, Jonas Steensgaard (Master thesis, 2019)Overvågning af søer har de seneste årtier fået større og større opmærksomhed. Dette skyldes de stadigt stigende udfordringer i forbindelse med at holde den antropogene påvirkning ved et minimum. Både naturlige sæsonvariationer, ...
