• Bypass of Booming Inputs of Urban and Sludge-Derived Microplastics in a Large Nordic Lake 

      Clayer, Francois; Jartun, Morten; Buenaventura, Nina T; Guerrero, Jose-Luis; Lusher, Amy (Peer reviewed; Journal article, 2021)
      Microplastic research, initially focusing on marine environments, left freshwater ecosystems largely unexplored. Freshwaters are also vulnerable to microplastics and are likely the largest microplastic supplier to the ...
    • Flood mitigation options to reduce flooding risks in Bjørkelangen town 

      Guerrero, Jose-Luis; Rasmussen, Jes Jessen (NIVA-rapport;7649, Research report, 2021)
      We assessed three different flood mitigation options, based on simple models, to reduce flooding problems in Bjørkelangen town. The mitigation options i) small debris dams, ii) re-meandering of Lierelva, and iii) restoration ...

      In the Norwegian River Monitoring Programme (Elveovervåkingsprogrammet) 20 rivers along the Norwegian coastline are monitored for chemical and hydrological parameters. It is a continuation of a former monitoring programme, ...
    • Parameter sensitivity analysis of a 1-D cold region lake model for land-surface schemes 

      Guerrero, Jose-Luis; Pernica, Patricia; Wheater, Howard; MacKay, Murray; Spence, Chris (Journal article; Peer reviewed, 2017)
      Lakes might be sentinels of climate change, but the uncertainty in their main feedback to the atmosphere – heat-exchange fluxes – is often not considered within climate models. Additionally, these fluxes are seldom measured, ...
    • Pipes or chimneys? For carbon cycling in small boreal lakes, precipitation matters most 

      de Wit, Heleen A; Couture, Raoul-Marie; Jackson-Blake, Leah; Futter, Martyn N.; Valinia, Salar; Austnes, Kari; Guerrero, Jose-Luis; Lin, Yan (Journal article; Peer reviewed, 2018)
      Are small lakes passive pipes transporting terrigenous organic carbon (dissolved organic carbon [DOC]), or chimneys for CO2 release in the landscape? Using a unique combination of 30‐yr measurements, sediment dating and ...
