The biocenosis of bathyal muds is characterised by a constant homoeothermy of around 13°C and an almost total absence of light. |
Many of them are saline, rich in organic and mineral muds and alkaline waters. Due to this, the health resort system is well-developed. |
At first glance the drained muds of the Blyth estuary were dotted with shelduck, redshank, curlew, wigeon, pintail and black headed gulls. |
We were in a coulee, which is like a slough but deeper and with slushier muds at the bottom. |
The basal conglomerates and the equivalent sands and muds on the interfluves are commonly ferruginized. |
These subterranean muds are being uplifted into steeply dipping, anticlinal structures cored by strike-slip faulting. |
