                        <gco:CharacterString>Die oberflächliche Sedimentschicht innerhalb der mesohalinen Brackwasserzone der Ems wurde nach Probenserien, die in den Monaten Mai 1952, August 1952 und Januar 1953 auf der Strecke zwischen dem Ostriesischen Gatje und Hilkenborg bei Weener entnommen sind, auf Grund der darin gefundenen dominierenden Nematodenarten mit begrenzter ökologischer Valenz zoniert.
Die mittlere untere Grenze des mesohalinen Brackwasserkörpers in Bodennähe konnte nicht einwandfrei mit der Methode erfasst werden.
Der bodennahe Schwerpunkt der Brackwasserzone liegt im Sommer östlich des Emdener Außenhafens. Er verlagert sich im Winter in den Bereich östlich der Knock.
Die mittlere obere Grenze des mesohalinen Brackwasserkörpers in Bodennähe befindet sich etwa in der Höhe von Leerort. Weiter stromaufwärts besitzt das Flussbett einen zunehmenden oligohalinen Charakter.
