    Notes: Deposits of the ancestral Rio Grande (aRG) belonging to the Camp Rice Formation are preserved and exposed in the uplifted southern portion of the Robledo Mountains horst of the southern Rio Grande rift. The sediments are dated palaeomagnetically to the Gauss chron (upper Pliocene). The lower part of the succession lies in a newly discovered palaeocanyon cut into underlying Eocene rocks whose margins are progressively onlapped by the upper part. Detailed sedimentological studies reveal the presence of numerous river channel and floodplain lithofacies, indicative of varied deposition in channel bar complexes of low-sinuosity, pebbly sandbed channels that traversed generally dryland floodplains and shifted in and out of the study area five times over the 1 Myr or so recorded by the succession. Notable discoveries in the deposits are: (1) complexes of initial avulsion breakout channels at the base of major sandstone storeys; (2) common low-angle bedsets ascribed to deposition over low-angle dunes in active channels; (3) palaeocanyon floodplain environments with evidence of fluctuating near-surface water tables. Sand-body architecture is generally multistorey, with palaeocurrents indicative of funnelling of initial avulsive and main fluvial discharge from the neighbouring Mesilla basin through a narrow topographic gap into the palaeocanyon and out over the study area. An avulsion node was evidently located at the stationary southern tip to the East Robledo fault during Gauss times, with aRG channels to the north flowing close to the fault and preventing fan progradation. Subsequent Matuyama growth of the fault caused (1) deposition to cease as the whole succession was uplifted in its footwall, (2) development of a thick petrocalcic horizon, and (3) fan progradation into the Mesilla basin. Parameters for the whole aRG fluvial system are estimated as: active single channels 2 m deep and 25 m wide; valley slope 0·24–0·065°; maximum mean aggradation rate 0·05 mm year–1; major channel belt avulsion interval 200 ky; individual channel recurrence interval 100 ky; minimum bankfull mean flow velocity 1·54 m s–1, minimum single-channel discharge 77 m3 s–1, bed shear stress 22·3 N m–2; and stream power 34·3 W m–2.

    Notes: The dynamic behaviour of sediment-laden underflows was examined in Peyto Lake, Alberta, Canada, which contains a midlake sill 7 m high. Sediment-laden underflows are driven by the downslope component of negative buoyant gravity multiplied by the current's thickness. Our measurements of wind, lake currents and water properties indicate that underflows pass over the sill due to the active storage of turbid suspension near the bottom in the deepest proximal region. Sill overflows occurred only when a hydrological threshold of the inflowing river was exceeded, causing quasicontinuous underflow and associated sedimentation in the distal region of the lake basin.

    Description: Benthic foraminifera (〉125 µm fraction) were analysed in sediment samples from Hole U1381C (08°25.7027′N; 84°09.48′W, 2064.6 m water depth) located off Costa Rica (East Pacific) and obtained during IODP Expedition 344. We analysed samples each 10-20 cm in the uppermost 55 meters. The relative abundance of the most abundant species in the uppermost 47 meters representing the last 650 ka was discussed in Diz et al. (2018). Here we provide the full counts for the first 55 meters of the Hole U1381C.

    Description: The bulk sedimentary nitrogen isotopic measurements and relative contribution of nitrogen were analysed in ODP Site 202-1242 (7º51.352'N, 83º36.418'W, 1364 meters water depth) located off Costa Rica, in the East Equatorial Pacific. A selection of samples between 84 and 125 meters composite depth representing the interval between 720 and 1040 ka were dried (45ºC), ground and homogenised using a zircon ball mil. About 20 mg of sample were measured for their nitrogen isotopic composition by using an Elemental Analyzer FlashEA 1112 coupled to a ThemoFinningan MAT 253 Isotope Mass Spectrometer. The nitrogen content of the sample was measured using a micro-elemental analyser Fisons Carlo Erba EA1108.
