We all are aware of this natural fact that fresh groundwater and surface water eventually meet and mix with salty marine waters in estuaries. Like many other zones in which one habitat merges into another, estuaries are typically highly biologically productive, with a greater diversity of animal and plant species than the fully freshwater or fully marine zones on either side. The ecological structure of estuaries is exquisitely variable, reflecting the shifting patterns of water depth, current strength and salinity.


Many estuaries host extensive colonies of worms and molluscs, such as oysters and mussels. As filter-feeders that strain their nutrients from passing water, these molluscs require access to fairly fast-flowing currents.

In the shallower subtidal areas with weak currents, where sunlight still penetrates to the benthos, submarine meadows tend to develop, comprising thick stands of sea-grasses . The stems of these plants tend to filter fine sediment from the water column; where these sediments settle, they are grazed by detritus feeders, which include a wide range of worms, sea snails and crabs. As the submarine meadows are traced up into the intertidal zone, they pass into intertidal salt marshes (in temperate zones) or (in the tropics) into mangrove swamps.

Leaving the estuaries the estuaries behind, it is estimated that about three-quarters of all life on Earth is to be found in the open oceans. This is not especially surprising when we recall that oceans comprise 99 per cent of all living space on the planet. To date , humans have directly explored less than 10 per cent of that space; most of the unexplored volume is far below the depth of sunlight penetration, in the cold and dark depths of the ocean, averaging about 3.7 kilometres deep and exceeding 11 kilometres in places. So far, scientists have documented nearly 200,000 marine species, but this is believed to be a small fraction of the total number that exists.

It is easy to be seduced by these numbers into imagining a marine paradise, untouched by humans. Sadly, this is far from the case. With the exceptions of some unusual microbes and tubeworms that thrive around hydrothermal events on the sea floor, most of the life in the cool, dark depths of the sea is dependent on the nutrients that ‘rain down’ from the photosynthetic zone above. And this zone is being ravaged by humankind, as we pollute the waters and remove the fish at unsustainable rates. As we drastically diminish biological activity in the zone of light penetration, we are surely wreaking untold havoc on life in the deeps, where the supply of cascading nutrients was always in rather delicate balance.
