STD
2005/06/07		 WETLAND_SURFACE_FORM PEAT_PLATEAU_BOG A <BOG> composed of perennially frozen peat rising abruptly about 1 metre from the surrounding unfrozen fen; peat plateau bog. The <SURFACE> is relatively flat and even, and commonly covers large areas. The peat was originally deposited in a non-permafrost environment and is associated in many places with collapse scar <BOG>s or fens. 11 IR [ECORC, Wetland Surface Forms, B07]  
STD
2005/06/07		 WETLAND_SURFACE_FORM POLYGONAL_PEAT_PLATEAU-
_BOG		 A perennially frozen <BOG> rising approximately 1 metre above the surrounding fen; polygonal peat plateau bog. The <SURFACE> is relatively flat, scored by a polygonal pattern of <TRENCH>s that developed over wedges of <ICE>. The permafrost and wedges of <ICE> developed in peat originally deposited in a non-permafrost environment. 12 IR [ECORC, Wetland Surface Forms, B05]  
STD
2005/06/07		 WETLAND_SURFACE_FORM SHALLOW_BASIN_MARSH A <MARSH> occurring in a uniformly shallow marsh depression or swale, having a gradual gradient from an often poorly defined edge to the deepest portion, and whose water levels fluctuate rapidly; shallow basin marsh. 13 IR [ECORC, Wetland Surface Forms, M11]  
STD
2005/06/07		 WETLAND_SURFACE_FORM SHORE_FEN A fen with an anchored surface mat that forms the <SHORE> of a pond or <LAKE>. The rooting zone is affected by the <WATER> of the <WATERBODY> at both normal and flood levels. 14 IR [ECORC, Wetland Surface Forms, F07]  
STD
2005/06/07		 WETLAND_SURFACE_FORM SHORE_MARSH A <MARSH> occupying the <REGION> between high and low water marks bordering semi-permanent or permanent <LAKE>s; shore marsh. The <MARSH>, usually found along protected <SHORELINE>s, behind barrier <BEACH>s in <LAGOON>s, on <ISLAND>s, or in embayments, is subject to flooding by a rise in the level of the <LAKE>, <WIND_WAVE>s, or <RUN_OFF>. 15 IR [ECORC, Wetland Surface Forms, M14]

In addition to the status and date information for each entry, a colour coding scheme highlights the database holding to which an entry belongs. The following highlight colours are used:

  • white - the entry is in the standard
  • yellow - the entry has been added to the register
  • pink - the entry has been submitted for inclusion in the register, but it is not approved
  • cyan - a deprecated entry that was originally either in the standard or was added to the register, but has since been deprecated

The following icons are used to identify items that have figures, modifications and/or clarification notes:

  • F n - has Figures and, if more than one figure, n figures
  • M - has Modifications
  • C - has Clarifications
