  • Using Groundwater Responses to Infer Recharge - Part 5

    Series Book 5 - Basics of Recharge and Discharge Series
    Analytical methods of assessing the response of groundwater levels to a range of factors, including elastic (barometric and tidal) influences in confined aquifers and recharge to unconfined aquifers due to infiltration of rain and other surface water, are presented. Responses in a confined aquifer to distant recharge events and the associated time lag is discussed. Also covered are responses to ... Read more

  • Groundwater Chemical Methods for Recharge Studies - Part 2

    Series Book 2 - Basics of Recharge and Discharge Series
    These notes are restricted to those geochemical methods which have been used to quantify rates of groundwater recharge. There have been two main approaches. The first involves the use of mass balances and mixing cell models, mainly using conservative (non-reacting) dissolved species. The methods range in complexity from simple back-of-the-envelope calculations (zero-dimensional chloride mass ... Read more

  • Catchment Scale Recharge Modelling - Part 4

    by TJ Hatton ...
    Series Book 4 - Basics of Recharge and Discharge Series
    This paper addresses the need to model recharge to groundwater systems at the scale of whole catchments. It looks at developing the right conceptual model of how water moves through a given landscape for both homogeneous and heterogeneous catchments. One-dimensional recharge models and three-dimensional recharge models are considered. Discussion of which recharge modelling approach to use take in ... Read more

  • Diel Vertical Migration of Zooplankton in Lakes and Oceans

    causal explanations and adaptive significances

    Series series Earth and Environmental Science (R0)
    Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover ...

  • Long Island Sound

    Prospects for the Urban Sea

    Series series Earth and Environmental Science (R0)
    The U.S. Ocean Commission Report identified the need for regional ecosystem assessments to support coastal and ocean management. These assessments must provide greater understanding of physical and biological dynamics than assessments at global and national scales can provide but transcend state and local interests. This need and timeliness is apparent for Long Island Sound, where a multi-state ... Read more

  • The Choanoflagellates

    Evolution, Biology and Ecology

    Choanoflagellates have three distinctive claims to fame: they are the closest, living, unicellular relatives of animals; they are a major component of aquatic microbial foodwebs; and one group is remarkable for its siliceous basket-like coverings. This landmark book offers a unique synthesis of over forty years of choanoflagellates research. Key areas are covered, from the phylogenetic evidence ... Read more
