  • Feasibility of water quality monitoring by remote sensing in the Waikato Region

    Lehmann, Moritz K.; Schallenberg, Lena A.; Allan, Mathew Grant (Environmental Research Institute, The University of Waikato, 2017)
    The Waikato Regional Council (WRC) has statutory environmental monitoring requirements, including commitments arising from the National Policy Statement for Freshwater Management and State of the Environment reporting. ...
  • A global database of lake surface temperatures collected by in situ and satellite methods from 1985–2009

    Sharma, S; Gray, DK; Read, JS; O’Reilly, CM; Schneider, P; Qudrat, A; Gries, C; Stefanoff, S; Hampton, SE; Hook, S; Lenters, JD; Livingstone, DM; McIntyre, PB; Adrian, R; Allan, Mathew Grant; Anneville, O; Arvola, L; Austin, J; Bailey, J; Baron, JS; Brookes, J; Chen, Y; Daly, R; Dokulil, M; Dong, B; Ewing, K; de Eyto, Elvira; Hamilton, David P.; Havens, K; Haydon, S; Hetzenauer, H; Heneberry, J; Hetherington, AL; Higgins, SN; Hixson, E; Izmest’eva, LR; Jones, BM; Kangur, K; Kasprzak, P; Köster, O; Kraemer, BM; Kumagai, M; Kuusisto, E; Leshkevich, G; May, L; MacIntyre, S; Müller-Navarra, D; Naumenko, M; Noges, P; Noges, T; Niederhauser, P; North, RP; Paterson, AM; Plisnier, P-D; Rigosi, A; Rimmer, A; Rogora, M; Rudstam, L; Rusak, James A.; Salmaso, N; Samal, NR; Schindler, DE; Schladow, G; Schmidt, SR; Schultz, T; Silow, EA; Straile, D; Teubner, K; Verburg, P; Voutilainen, A; Watkinson, A; Weyhenmeyer, GA; Williamson, CE; Woo, KH (Nature Publishing Group, 2015-03-17)
    Global environmental change has influenced lake surface temperatures, a key driver of ecosystem structure and function. Recent studies have suggested significant warming of water temperatures in individual lakes across ...
  • Hindcasting water clarity from Landsat satellite images of unmonitored shallow lakes in the Waikato region, New Zealand

    Hicks, Brendan J.; Stichbury, Glen; Brabyn, Lars; Allan, Mathew Grant; Ashraf, Muhammad Salman (Springer, 2013)
    Cost-effective monitoring is necessary for all investigations of lake ecosystem responses to perturbations and long-term change. Satellite imagery offers the opportunity to extend low-cost monitoring and to examine spatial ...
  • Landsat remote sensing of chlorophyll a concentrations in central North Island lakes of New Zealand

    Allan, Mathew Grant; Hamilton, David P.; Hicks, Brendan J.; Brabyn, Lars (Taylor & Francis, 2011)
    We investigated the use of Landsat Enhanced Thematic Mapper (ETM) imagery to synoptically quantify chlorophyll a (chl a) concentrations. Two adjoining pairs of images of the central North Island were acquired on two different ...
  • Light attenuation characteristics of glacially-fed lakes

    Rose, Kevin; Hamilton, David P.; Williamson, CE; McBride, Chris G.; Fischer, JM; Olson, MH; Saros, JE; Allan, Mathew Grant; Cabrol, N (American Geophysical Union, 2014)
    Transparency is a fundamental characteristic of aquatic ecosystems and is highly responsive to changes in climate and land use. The transparency of glacially-fed lakes may be a particularly sensitive sentinel characteristic ...
