Havsvikar

Havsvikar is a coastal landform describing a sea inlet or bay along the coastline. In Swedish geography, a havsvik is a pronounced indentation in the shore that opens to the sea and is sheltered by headlands or peninsulas. Havsvikar can vary from small coves to larger bays and may contain beaches, mudflats, or rocky bottoms, with water that is comparatively calm relative to the open sea.

Formation and dynamics: Havsvikar form mainly through wave erosion and differential rock resistance, with softer rocks wearing away faster to produce an indentation. Over geological timescales, changes in sea level, glacial history, sediment supply, and longshore drift influence their size, depth, and sediments. Their mouths regulate water exchange with the open sea, and sedimentation can gradually fill them in if supply exceeds removal.

Ecology and human use: The sheltered waters of havsvikar support diverse marine life and serve as nurseries for fish and invertebrates. They are often used for recreation, boating, and coastal communities may rely on them for fishing harbors or small ports. Water quality and sediment dynamics can be sensitive to human activities and natural events.
