Le Cann b a IFREMER, Laboratoire d’Oc�eanographie Physique et Spatiale (LOPS), IUEM, Brest, France b CNRS, Laboratoire d’Oc�eanographie Physique et Spatiale (LOPS), IUEM, Brest, France ARTICLE INFO ABSTRACT Keywords: We investigate the nearly barotropic oscillations recently observed around the Saint Pierre and Miquelon (SPM) Barotropic modelling archipelago. They were recorded by two ADCPs at about 30 m depth during winter and spring 2014. These Wind induced oscillations oscillations were the dominant signal on the currents with a period of 2–4 days. Our analysis shows that these Continental shelf wave oscillations were triggered by the wind. To investigate these oscillations, a 2D numerical model was implemented Saint Pierre and Miquelon archipelago at a regional scale. The results from a realistic simulation confirmed the impact of wind forcing on ocean dy Newfoundland namics in the region. They also showed amplificationof these oscillations around SPM, particularly in the north- west of the archipelago and near Burin Peninsula. Analyses suggested the influence of continental shelf wave dynamics at a ‘regional’ scale. This regional wave then triggers a ‘local’ scale continental shelf wave propagating anticyclonically around SPM in ~2 days. Schematic modelling simulations with periodic wind stress forcing and relaxation after a gust of wind show a strong current response in this region with a wind stress periodicity centred around 2 days, which is attributed to resonance in the SPM area. -

Large Diurnal Bottom Temperature Oscillations Around the Saint Pierre
www.nature.com/scientificreports OPEN Large diurnal bottom temperature oscillations around the Saint Pierre and Miquelon archipelago Received: 30 January 2017 Pascal Lazure, Bernard Le Cann & Marion Bezaud Accepted: 28 August 2018 Here, we report large, near-daily oscillations of near-bottom temperatures, with ranges of up to 11.5 °C Published: xx xx xxxx at depths of 30–60 m in September 2011 around the Saint Pierre and Miquelon archipelago (south- eastern Canada). These oscillations were detected on velocity and temperature profles from moorings in Miquelon Bay and on an array of near-bottom temperature sensors around the archipelago. The oscillations coincided with the seasonal stratifcation period. In addition to their remarkable range, they exhibited a near-diurnal period centred on the O1 tidal component (~26 h), contrasting with the dominant semi-diurnal sea-level periodicity in the area. They appear to be the manifestation of an internal wave, triggered by the diurnal surface tide and trapped by the bathymetric confguration of the area. We argue that the archipelago is nearly resonant for island-trapped waves at near-diurnal frequencies. Our data demonstrate that these coastal-trapped waves propagate clockwise around the archipelago in roughly two days, and thus approximate an azimuthal, mode 2 pattern. Simplifed calculations show that cross-shore motions are bottom-amplifed. In addition, bottom friction acts to rotate the axes of the diurnal tidal current ellipses with depth, and this combination of efects explains the large range of observed bottom temperature oscillations. Large seabed temperature oscillations have been observed in shallow waters at many locations around the world. -

GPS telemetry data of fifteen individuals of alcids (5 Razorbills 6 Common Murres and 4 Puffins) were analyzed to determine their distribution during the breeding period of 2016 at Saint Pierre and Miquelon Archipelago (SPM). Two analytical methods (threshold and a switching state-space model) were used to identify behavioral modes and foraging areas. We compared foraging movements and estimated the overlap between the species. -
