We present initial results of very high resolution Atacama Large
Millimeter/submillimeter Array (ALMA) observations of the $z$=3.04
gravitationally lensed galaxy HATLAS J090311.6+003906 (SDP.81). These
observations were carried out using an extended configuration as part of
Science Verification for the 2014 ALMA Long Baseline Campaign, with baselines
of up to 15 km. We present continuum imaging at 151, 236 and 290 GHz, at
angular resolutions as fine as 23 milliarcseconds (mas; corresponding to an
un-magnified spatial scale of 180 pc at z=3.042). The ALMA images clearly show
two main gravitational arc components with emission tracing a radius of 1.5
arcseconds. We also present imaging of CO(10-9), CO(8-7), CO(5-4) and H2O line
emission. The CO data has an angular resolution of 170 mas and the emission is
found to broadly trace the gravitational arc structures. We detect H2O line
emission but only using the shortest baselines. The ALMA continuum and spectral
line fluxes are consistent with previous Plateau de Bure Interferometer and
Submillimeter Array observations despite the increase in angular resolution.
Finally, we detect weak unresolved continuum emission at all three observed
frequencies from a position that is spatially coincident with the centre of the
foreground lensing galaxy.
