ARCHYD dataset - ARCachon bay HYDrologic monitoring program

The ARCHYD dataset, which have been collected since 1988, represents the longest long-term hydrologic data sets in Arcachon Bay. The objectives of this monitoring programme are to assess the influence of oceanic and continental inputs on the water quality of the bay and their implications on biological processes. It also aims to estimate the effectiveness of management policies in the bay by providing information on trends and/or shifts in pressure, state, and impact variables.

Sampling is carried on stations spread across the entire bay, but since 1988, the number and location of stations have changed slightly to better take into account the gradient of ocean and continental inputs. In 2005, the ARCHYD network was reduced to 8 stations that are still sampled by Ifremer to date. All the stations are sampled at a weekly frequency, at midday, alternately around the low spring tide and the high neap tide. Data are complementary to REPHY dataset. Physico-chemical measures include temperature, salinity, turbidity, suspended matters (organic, mineral), dissolved oxygen and dissolved inorganic nutrients (ammonium, nitrite+nitrate, phosphate, silicate). Biological measures include pigment proxies of phytoplankton biomass and state (chlorophyll a and phaeopigment).

Credit: The acquisition of this dataset was performed in the frame of the ARCHYD network, created and implemented by Ifremer since 1988. It was supported by the French Water Agency Adour-Garonne, involved in the monitoring of coastal waters for all the parameters which are used for WFD evaluations since 2007 and by the Syndicat Intercommunal du Bassin d’Arcachon (SIBA) since 2016. The people cited in the contributors include past and present regional coordinators of the ARCHYD, key analysts in physico-chemical measurements and individuals who contributed to the data through their personal expertise. Other contributors such as samplers and other analysts are also gratefully acknowledged.
