English

Subject field(s)
  • Climatology
  • Ecology (General)
  • Plant and Crop Production
CONT

The [coastal wetland response model] integrated physical and ecological data to evaluate the response of wetland vegetation communities over time to climate change. Data included climatic exposure(e. g., temperature), modelled hydrodynamic data(e. g., water levels), land use, digital elevation models, and data collected from study site-level vegetation surveys...

Domaine(s)
  • Climatologie

  • Cultures (Agriculture)
CONT

Le modèle [de réaction des milieux humides côtiers] intègre des données écologiques et physiques afin de prédire la réaction de la communauté végétale du milieu aux changements climatiques au fil du temps. Ces données comprennent notamment l'exposition climatique (p. ex. la température), les données hydrodynamiques modélisées (p. ex. les niveaux d'eau), l'aménagement des terres environnantes, les modèles numériques d'élévation, et les données recueillies dans le cadre des relevés sur place de la végétation.

Record 2 2020-10-22

English

Subject field(s)
  • Ecology (General)
CONT

The biotic productivity of these coastal ecotones is extremely high, rivaling the most intensely cultivated farmlands. Several factors account for this : abundant nutrients; conservation, retention, and efficient recycling of nutrients among benthic, wetland, and pelagic habitat(i. e., coupling of subsystems) ;consortia of phytoplankton, benthic microalgae and macroalgae, seagrasses, mangroves, and fringing saltmarsh vegetation that maximize available light and space; tidal energy and circulation.

Record 4 2008-07-10

English

Subject field(s)
  • Geomorphology and Geomorphogeny
CONT

Because of the low surface gradient..., a wetland vegetation(dominated by grasses and sedges) developed rather quickly.

CONT

A low surface gradient was caused by an occurrence of peripheral parts of the ice cover on a low plain covered by friable water-saturated sediments similar to those lying on the modern continent and shelf.

OBS

low surface gradient: term used at Natural Resources Canada - Earth Sciences Sector.

French

Domaine(s)
  • Géomorphologie et géomorphogénie
CONT

Des facteurs secondaires ont pu [...] jouer un rôle dans l'aggravation du phénomène et sa localisation. Ces facteurs ce sont : le faible gradient de surface qui a permis la stagnation, ou plutôt la régénération sur place pendant plusieurs heures des cumulo-nimbus, le relief et la présence d'une ville coiffée de sa cloche thermique, qui ont contribué à localiser le phénomène.

CONT

Le faible gradient en surface dans toute la municipalité se traduit par un mauvais drainage superficiel.

OBS

S'oppose à «fort gradient en surface».

OBS

profil surbaissé : terme en usage à Ressources naturelles Canada - Secteur des sciences de la Terre.

Record 5 2000-08-15

English

Subject field(s)
  • Peat and Peat Bogs
  • Soil Science
  • Hydrology and Hydrography
  • Ecosystems
DEF

Peatland with the water-table usually at or a few centimetres above or below the surface.

DEF

A wetland area similar to a bog, except for its vegetation which is generally more varied and richer because of the higher mineral content of water percolating through it.

OBS

fen: term used by Parks Canada.

French

Domaine(s)
  • Tourbières
  • Science du sol
  • Hydrologie et hydrographie
  • Écosystèmes
DEF

Milieu humide moyennement acide, généralement riche en éléments minéraux et alimenté par l'eau de ruissellement; ce milieu possède ordinairement une végétation plus variée que la tourbière haute.

DEF

Tourbière où la nappe phréatique se situe généralement à la surface ou quelques centimètres au dessous.

OBS

tourbière basse; tourbière minérotrophe; tourbière immergée; tourbière alcaline : termes en usage à Parcs Canada.

OBS

fen : Source : Le système de classification des terres humides du Canada du groupe de travail national sur les terres humides.

Record 6 1999-06-30

English

Subject field(s)
  • Water Pollution
CONT

The first of its kind in Canada, the Dunkers Flow Balancing System treats polluted stormwater discharged from an outfall located at the base of the Bluffs. A series of five cells, created by using curtains suspended from floating pontoons, are used to settle contaminants found in stormwater. During a rainfall, stormwater enters the first cell and moves through three other cells before entering the wetland area. The wetland, constructed in the fifth cell, provides final cleansing by the vegetation before the water is discharged into Lake Ontario.

OBS

The system was developed by Mr. Karl Dunkers of Stockholm, Sweden.
