Target class: brackish water stage Context triple: [Post-Littorina Sea, instanceOf, brackish water stage]
-
A.
freshwater tidal estuary
A freshwater tidal estuary is a low-lying river mouth region where freshwater flows are influenced by ocean tides, causing regular water-level and flow reversals without significant saltwater intrusion.
-
B.
estuary
An estuary is a coastal water body where freshwater from rivers and streams mixes with saltwater from the ocean, creating a dynamic and nutrient-rich environment.
-
C.
post-glacial stage of the Baltic Sea
chosen
The post-glacial stage of the Baltic Sea is the developmental phase following the last Ice Age during which the retreat of continental ice sheets, isostatic land uplift, and changing sea levels transformed the basin from a glacially dammed lake into a brackish marginal sea with evolving coastlines and ecosystems.
-
D.
tidal river segment
A tidal river segment is a stretch of river whose water level, flow, and salinity are directly influenced by periodic tidal fluctuations from a connected estuary or sea.
-
E.
perennial stream
A perennial stream is a watercourse that flows continuously throughout the year under normal climatic conditions, sustained by consistent sources such as groundwater, springs, or upstream inputs.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
