      "schema:description": "The Zooplankton Ecology Group of the University of the Basque Country initiated in 1997 a monitoring programme in the estuaries of Bilbao and Urdaibai (the latter also called estuary of Mundaka). Sampling is carried out monthly at the salinity sites of 35-34, 33, 30 and 26 (the last one only in Urdaibai) to obtain vertical profiles of temperature, salinity and dissolved oxygen, and to take samples for Chlorophyll a determination and zooplankton analysis. Water samples are obtained with oceanographic bottles and zooplankton samples by horizontal hauls with 200 µm plankton-nets, both at mid depth below the halocline.\r\nThe estuaries of Bilbao (43 23 N 3 W) and Urdaibai (43 22 N, 2 43 W) are two shallow meso-macrotidal systems located on the Basque coast (Bay of Biscay), at middle latitudes of the northeastern Atlantic. The estuary of Bilbao is an urban system constituted by a narrow (50 to 150 m), ca. 15 km long, 2 to 9 m deep man-made channel and a wider (ca. 3.8 km) and deeper (10 to 25 m) embayment in the lower end. Most of the estuary shows noticeable water-column stratification and a permanent salt wedge is found in the bottom layer, where salinities are usually =30. The water column is partially mixed at the outer estuary, partially mixed to stratified at the intermediate zone and stratified at the inner estuary. The estuary of Urdaibai is also a short (12.5 km) system, but shallower (mean depth of 3 m) than the estuary of Bilbao. The central channel is bordered by salt marshes at its upper (15 m wide) and middle reaches and by relatively extensive intertidal flats (mainly sandy) and sandy beaches at its lower reaches (ca. 1 km wide). The watershed area is relatively small in relation to the estuarine basin, and river inputs are usually low in relation to the tidal prism. As a consequence, most of the estuary is marine-dominated, with high-salinity waters in the outer half and a stronger, decreasing axial gradient of salinity towards the head.",
