title: Data from: Influence of Carbene and Phosphine Ligands on the Catalytic Activity of Gold Complexes in the Hydroamination and Hydrohydrazination of Alkynes

description: ABSTRACT: Through kinetic measurements, catalytic and stoichiometric experiments, as well as DFT calculations, we compare the catalytic activity of gold complexes supported by a variety of ligands (R3P, NHC, CAAC-5, CAAC-6, BiCAAC) in the hydroamination and hydro-hydrazination of alkynes. This study provides a rationale for the superior efficiency of a gold complex bearing a bicyclic (alkyl)(amino)carbene (BiCAAC). We demonstrate that this ligand motif, which is readily available, provides a durable gold catalyst able to compete with sophisticated state-of-the-art phosphine and NHC ligands, which feature secondary interaction capabilities.

title: Data from: Enhanced surf zone and wave runup observations with hovering drone-mounted LiDAR

description: LiDAR data are collected with a truck-mounted terrestrial LiDAR (1550 nm Riegl VMZ-2000) and a drone-mounted 905 nm Riegl miniVUX-1UAV LiDAR. Pressure data is collected with Paroscientific model 245A-102 sensors combined with custom electronics. Data are post-processed in and available in MATLAB (2020) format.
description: The Drone LiDAR data contained in this object were obtained during the Storm CoAstal Response Project (SCaRP) field experiment of Winter 2019-2020. The study was conducted at Torrey Pines State Beach in San Diego, California, USA. The gently-sloped mixed cobble and sand beach was instrumented with a transect of buried pressure sensors extending from the cobble-covered upper beach to ~110 m offshore. A drone-mounted LiDAR hovered at 20 m above the water roughly 40 m offshore, and a truck-mounted terrestrial LiDAR (elevation 6.3 m, NAVD88) parked on an elevated road above the back beach. Data were collected during high tide (~MHHW, 1.57 m NAVD88) from 1800-1924 UTC 14 December 2020 and 1700-1920 UTC 24 February 2020. The dataset includes LiDAR derived 'time-stacks' from both LiDAR instruments; wave runup statistics, spectra, and time series for each time-stack; and pressure sensor surface-corrected time series. Abstract: We demonstrate that a hovering, drone-mounted laser scanner (LiDAR) paired with a survey-grade satellite and inertial positioning system measures the wave transformation across the surf zone and the resulting runup with accuracy almost equal to a stationary truck-mounted terrestrial LiDAR. The drone, a multi-rotor small unmanned aircraft system (sUAS), provides unobstructed measurements by hovering above the surf zone at 20 m elevation while scanning surfaces along a 150 m-wide cross-shore transect. The drone enables rapid data collection in remote locations where terrestrial scanning may not be possible. Allowing for battery changes, about 17 minutes of scanning data can be acquired every 25 minutes for several hours. Observations were collected with a wide (Hs = 2.2 m) and narrow (Hs = 0.8 m) surf zone, and are validated with traditional land-based survey techniques and an array of buried pressure sensors. Thorough post-processing yields a stable (mean standard deviation = 1.7 cm) back beach topography estimate comparable to the terrestrial LiDAR (mean standard deviation = 0.8 cm). Statistical wave properties and runup values are calculated, as well as bathymetry inversions using a relatively simple nonlinear correction to wave crest phase speed in the surf zone, illustrating the utility of drone-based LiDAR observations for nearshore processes.

title: HDSS RR1308 Cruise Data. In Hydrographic Doppler Sonar System (HDSS): Acoustic ocean current profiling data from the R/V Revelle

description: Port of departure: Kaohsiung, Taiwan Port of arrival: Palau, Republic of Palau The Hydrographic Doppler Sonar System (HDSS) on the R/V Revelle provides profiles of absolute ocean current and acoustic scattering strength in support of scientific operations. The HDSS consists of a 50 kHz Doppler sonar which returns data in a depth range between 20 m and 700-1100 m (depending on conditions), and a 140 kHz Doppler sonar which returns data in a depth range between 20 m and 150-350 m (depending on conditions). The system was created to provide measurements with higher depth resolution than is available from commercial Doppler sonars. Both the acoustic pulse length and the angular width of an acoustic beam affect depth resolution. HDSS uses large transducers to get narrower beams and greater power to get greater range without sacrificing vertical resolution. Just as ocean bathymetry is routinely collected from research vessels, the HDSS has the parallel tasks of monitoring ocean currents and acoustic scattering wherever the R/V Revelle sails, while simultaneously supporting individual science missions. The established policy is to have the system running and recording data at all times that the ship is underway, unless restricted by political regulation or acoustic interference.
