New Scientific Results reported by our customers[new feature, introduced 30 May 2006]
[This page is updated as users provide spectacular results from their work, using our instruments.]
LISST and FLOC Camera Agreement Reported:
Ole Mikkelsen (University of Wales, Bangor), together with Paul Hill
from Dalhousie University, Tim Milligan from Bedford Institute of
Oceanography and Robert Chant from Rutgers University, compare in situ
median floc sizes from a LISST-100C with a digital floc camera
(DFC). They report A) Larger median floc sizes from the DFC than
from the LISST because the DFC measures flocs >125 µm while the
LISST measures from 2.5 to 500 µm. B) Median diameters computed
from the overlapping size bins (125-500 µm) are the same, effectively
demonstrating that the two instruments size particles in a similar
manner. C,D) In the region of overlap the size spectra generally
have the same shape and can be merged to a single spectrum covering
sizes > 2.5 µm. See Mikkelsen et al. (2005): In situ particle size distributions and volume concentrations
from a LISST-100 laser particle sizer and a digital floc camera. CSR
25: 1959-1978, for more details.

Combined LISST-FLOC and LISST-100X(Type B) VSF Reported:
Dr. Emmanuel Boss (U Maine) uses LISST-100 instruments to extend
measurement of the Phase Function
to lowest ever angles, revealing a flattening demanded by symmetry (but
not seen before; presented at the Ocean Sciences Meeting, Hawaii,
2006): [In the figure, black dots are data from a LISST-FLOC and
red dots are from a LISST-100, Type-B.]
