      ROUTE BOIRO – A POBRA DO CARAMIÑAL SUNDAY, MAY 16 At this stage we walk through the Serra do Barbanza from Boiro to A Pobra do Caramiñal, in a very complete route in which we cross ancient roads that lead to ancient castles such as Vitres, which guarded the estuary of pirate incursions. We also visit beautiful natural corners such as the Pedras Continue reading Day 2 – Barbanza.   ABSTRACT Using stable isotope analysis, this study examined the potential food sources of the Japanese scallop, Patinopecten (Mizuhopecten) yessoensis (Jay) and determined whether the isotopic ratios inferred from tissues of cultured scallops varied according to .

The Arosa estuary is the largest in the region of Galicia, NW Spain. The approximate coordinates are longitude 08°50′00″W, latitude 42°30′00″N. A map of the area is shown in Fig. Samples were collected at different locations around the Arosa estuary and were lyophilised before analysis.

INTRODUCTION The Ria de Arosa (Fig. 1) is the largest ( km2) of a series of Cord-like bays in northwestern Spain. The system is at present being subjected to intensive research on the effects ofupwelling and massive mussel aquaculture on the ecosystem structure and function (Perez & Roman, ; Tenore et al., m press).

Peracarid Bottom sediments of the Ria de Arosa book inhabit many marine benthic habitats and are good indicators of environmental conditions. There is, however, a lack of information about diversity and distribution of peracarid crustaceans on the shallow subtidal sediments of the Galician rias.

In the summer of27 subtidal stations were sampled in the Ría de Aldán, a ria on the southern margin of the mouth of the. The metals are trapped mainly in the sediment of two estuary zones, just before they reach the Arosa Ria.

The first zone is located at the estuary head, where estuarine mixing occurs and the SPM from the Ulla River contributes Cu, Mn, Ni, and Zn, while the Sar River discharges urban waste and Cr.

Troncoso. The geo-destination, Ría de Arousa, contains the municipalities: A Illa de Arousa, A Pobra do Caramiñal, Boiro, Cambados, Catoira, Dodro, Meaño, Meis, O Grove. Gassy sediments in the Ría de Arousa are preferentially distributed in areas of muddy seabed sediments.

The close relationship between seabed sediment parameters and gas distribution is here studied in detail to establish better constraints on the presence of gas. Discriminant analysis was applied to the textural and compositional characteristics of seabed sediment samples to classify.

Coastal and estuarine intertidal sediments are commonly colonized by dense populations of microphytobenthos. Due to wind and tides, important fractions of microphytobenthic populations may be buried.

A mathematical model describing the depth variation of chlorophyll a in intertidal sediments was developed and experimentally tested. Direct and indirect evidence of the presence of shallow gas have been identified in the sediments of the internal part of the Ría de Arosa (NW of Spain).

Sub-bottom and echo sounder records reveal pockmark-like features and gas seeps in the water column. Seismic and sub-bottom profiler records have also been collected. Isla de Arosa (or Illa de Arousa) The isla de Arousa is in the province of Ponteverda and is reached by a carriageway that spans the few hundred yards between the island and the mainland.

A Ria de Arousa é a maior das rias da Galiza e de toda a parte das Rias Baixas e está situada entre a península do Barbanza (província da Coruña) a norte, e a península do Salnés (província de Pontevedra) a sul.

It is part of the Rias Baixas and is located between the estuary of Muros and Noia to. The metal content measured in surface sediment and suspended particulate matter (SPM) samples collected from the Ulla River estuary (NW Spain) showed evidence of contamination by Cr, Cu, Mn, Ni, and Zn, but not by Cd, Fe, and Pb.

The metals are trapped mainly in the sediment of two estuary zones, just before they reach the Arosa Ria. Remains are scattered on a rocky bottom. No sediment: Galicia - Punta o Boi, Picacho reef: Spain Victoria: Some pottery and metalic remains.

The Venus fasciata community was present in clean coarse sediments of the outer ria, the Venus gallina and Tellina fabula-Tellina tenuis communities in the fine-sand bottoms at the centre and margins of the ria, a transition assemblage between the Venus fasciata and the Venus gallina communities in the medium-sand sediments, and a mix of.

Measurements of feeding rate and absorption efficiency were performed to assess the nutritional value of sedimentary organics combined with phytoplankton for raft mussels (Mytilus galloprovincialis Lmk) in Ria de Arosa (Galicia, N.W.

Spain). The first animal was collected from “A Tiñosa” (Ria de Arosa, Galicia, Spain) on a rocky bottom between Clavelina lepadiformis colonies, at a depth of 24 metres (42°N, °W).

The other worm was found on stones in “Petón Bajo” (Ria de Arosa, Galicia, Spain), at a depth of 16 metres (42°N, °W). This results in a high (ca. 14%) organic content of silty bottom muds and results in a low diversity and biomass of a "pollution" infaunal benthos (Tenore et al., ).

Sediment changes restrict the distribution of some demersal fishes and may adversely affect scallop recruitment in the Ria de Arosa. The biofacies distribution appears to be closely related to the sediment input pattern into this bay.

Ria de Arousa. The Ria de Arousa is another well-known ria. It is located on the northern Atlantic coast of Spain, in the region of Galicia.

It is the largest estuary of Galicia, measuring 7 miles wide and 14 miles long. It is deepest at the mouth of the estuary, reaching feet in depth.

Ria de Arousa is also filled with several islands and. feces and pseudofeces that once ejected, settle to the bottom in the immediate vicinity of the farm.

The result is an organic enrichment of the benthos. This enrichment is generally minor in comparison to that associated with fed aquaculture.

The inner part can be considered an estuary from both hydrographic and the resulting sedimentological considerations, with the main estuarine processes being confined to the inner relatively small brackish water zone.

Macrobenthic polychaete distributions were studied along the soft-bottoms of the Ensenada de San Simón (Galicia, NW Spain). Results suggest that the distribution and abundance of polychaetes in the inlet were highly dependent on depth, sediment characteristics (grain size, organic matter and calcium carbonate content) and bottom water temperature.De Casabianca et al.

argued that the concentration of dissolved inorganic nitrogen did not vary much as a function of the presence or absence of a benthos, but rather in recycling of nutrients either in bottom sediments or in the water column. Thus, the effects of the benthos on pelagic production are two fold: supplying nutrients directly, and.• Ria de Aveiro, Portugal • Ria de Arousa, Galicia, Spain.
