Auteur(s): Delanne Hubert-Alexandre , Dans une première partie, l'auteur témoigne de sa sensibilité à la question du développement durable et à ses incidences dans le domaine de l'architecture, par l'intermédiaire de la norme HQE (Haute Qualité Environnementale). Dans cette perspective, il développe, ensuite, une analyse critique de l'évolution du logement social en France, et présente l'idée d'habitat intermédiaire, comme solution de compromis entre les aspirations individualistes d'une part, et la nécessité de lutter contre l'étalement urbain, d'autre part. Le quartier Vigon, à Mimizan (Landes), lui semble propice à une expérimentation de cette forme d'habitat, dans le souci de s'adapter à la diversité des modes de vie de ses occupants, tout en préservant une densité urbaine suffisante et en intégrant, dans la construction, les principes de la HQE.

Auteur(s): Parent Pierre , L'auteur étudie les différentes conceptions et formes architecturales qui ont prévalu, après guerre, en matière de logement social, en les replaçant dans leur contexte socio-économique et idéologique. L'analyse critique qu'il en fait, le conduit à chercher et à proposer une solution alternative à celles issues du Mouvement moderne, jugées trop réductrices. Pour l'auteur, la fiabilité du logement social suppose la prise en compte de la complexité urbaine et implique son intégration au coeur même de la ville.

Impulsive or transient sounds of short duration and of high intensity constitute one of the criteria for defining good ecological status for descriptor 11 relating to the pressure of noise generated by human activities within the framework of the MSFD (D11C1). Good ecological status for sound energy is achieved when the risks of acoustic disturbance, excess mortality from sound exposure and reduction in communication distances of mysticetes are cumulatively low or moderate. For this, the spatial distribution, the temporal extent and the acoustic levels of the sources of anthropogenic impulsive sound must not exceed the levels harmful to the populations of marine animals. These criteria are evaluated at the scale of the marine sub-region for the “English Channel and North Sea”, “Celtic Seas” and “Western Mediterranean” regions; and at the scale of the "North" and "South" subdivisions in the "Bay of Biscay" sub-region. One of the indicators selected for the evaluation of criterion D11C1 is the spatial distribution of impulse emissions (D11C1.2). The pressures considered for the evaluation of the criterion are: acoustic emissions from air guns; acoustic emissions from impulsive sources other than air guns; emissions from non-impulsive (transient) sources; underwater explosions; emissions due to pile driving. The data used for the calculation of this indicator are declarative emissions data traced by the operators of the activities generating impulsive noise.

Continuous sound is one of the criteria for defining good ecological status for descriptor 11 relating to the pressure of noise generated by human activities in the context of the MSFD (D11C2). Good ecological status for sound energy is achieved when the risks of acoustic disturbance, excess mortality from sound exposure and reduction in communication distances of mysticetes are cumulatively low or moderate. For this, the spatial distribution, the temporal extent and the acoustic levels of continuous anthropogenic sounds must not exceed levels harmful to populations of marine animals. These criteria are assessed at the scale of the marine sub-region for the "Channel and North Sea", "Celtic Seas" and "Western Mediterranean" regions; and at the scale of the "North" and "South" subdivisions in the "Bay of Biscay" sub-region. One of the indicators selected for the evaluation of criterion D11C2 is the spatial distribution of annual ambient noise for the one-third octave band centered on 125 Hz (D11C2.2). The pressure considered for the evaluation of the criterion is the noise generated by maritime traffic, mainly in its trade and transport component which is subject to regulatory oversight by automatic identification system (AIS). The data used for the calculation of this indicator are in situ noise data (MAMBO device) and maritime traffic data (Lloyd’s).

The PHYTOBS-MARCOBOLO dataset comprises long-term time series on marine microphytoplankton, from 2003 to 2021, along the entire French metropolitan coastline. Microphytoplankton data cover microscopic taxonomic identifications and counts. The PHYTOBS-MARCOBOLO dataset corresponds to a dataset extracted from the PHYTOBS network (DOI:10.17882/85178). The PHYTOBS network provides the scientific community and stakeholders with validated and qualified data on the biomass, abundance and composition of marine microphytoplankton in coastal and lagoon waters, with the aim of supporting scientific research. PHYTOBS-MARCOBOLO is a dataset used as part of the Horizon Europe MARCO-BOLO project (https://marcobolo-project.eu/), in which we are currently working to understand and analyze multi-decadal trends in coastal and marine biodiversity on a European scale. The PHYTOBS-MARCOBOLO dataset gathers data from 18 sampling sites, selected from the PHYTOBS-Network dataset according to requirements of time series quality and geographical location of sampling sites established as part of the MARCO-COLO project. This dataset was also formatted according to a template imposed for the European project.

The grid is based on proposal at the 1st European Workshop on Reference Grids in 2003 and later INSPIRE geographical grid systems. The sample grid available here is part of a set of three polygon grids in 1, 10 and 100 kilometres. The grids cover at least country borders and, where applicable, marine Exclusive Economic Zones v7.0, http://www.marineregions.org. Note that the extent of the grid into the marine area does not reflect the extent of the territorial waters.

L’objectif général de ce projet de thèse est d’analyser et d’évaluer les données sources (actuelles et potentielles) des matrices de changements d’occupation du sol afin d’améliorer la robustesse de l’inventaire. Il s’agit d’expertiser par une démarche scientifique la pertinence des travaux réalisés annuellement pour l’inventaire UTCATF. En particulier, il s’agit de comprendre les causes des incertitudes des données sources ; compiler les données disponibles et leurs métadonnées ; étudier qualitativement les dynamiques paysagères décrites ; et redéfinir un cadre méthodologique permettant d’estimer des taux de changements plus pertinent.

ABSTRACT : Time series of the monthly means of potential temperature, salinity and potential density recorded on the HydroChanges consecutive moorings in the Gulf of Lion (41° 59.0' N 04° 55' E) few meters above the bottom (~2320m), between 2006 and 2011. N.B.: data from 2003 to 2006 exist but moorings are yet to be recovered. Observing strategy Mooring with 1 Seacat SBE37 and usually one currentmeter. Seacat SBE37 fitted with pump and pressure sensor for accurate computation of the salinity, and mostly sent to recalibration at SeaBird after their deployment.
