MORE LISST STUFF WILL BE HERE SOON.
IN THE MEANTIME, YOU CAN CLICK ON THE LINK BELOW AND CHECK OUT THE WEB SITE OF THE MANUFACTURER OF THE LISST INSTRUMENT SERIES SEQUOIA SCIENTIFIC INC..


WE, AT THE COWEN LAB, ARE THE PROUD OWNER OF THE FIRST EVER DEVELOPED LISST-DEEP. THIS INSTRUMENT IS CAPABLE OF MEASURING THE PARTICLE VOLUME DISTRIBUTION, WHICH CAN BE CONVERTED TO PARTICLE AREA OR NUMBER DISTRIBUTIONS. THE MEASUREMENTS ARE BASED ON THE LIGHT SCATTERING MEASUREMENTS AT DIFFERENT ANGLES. OUR INSTRUMENT MEASURES PARTICLES FROM 1.25 TO 250 UM.TO LEARN MORE ABOUT HOW LISST TECHNOLOGY WORKS, CHECK SEQUOIA SCIENTIFIC'S WEB SITE.

SAMPLE:
BELOW YOU SEE AN EXAMPLE OF WHAT KIND OF PRODUCT THE LISST-DEEP CAN PRODUCE. THIS IS A PARTICLE SIZE DISTRIBUTION MEASURED AT ONE STATION IN THE GULF OF CALIFORNIA IN GUAYMAS BASIN PLOTTED AGAINST DEPTH. GUAYMAS BASIN IS SUBJECT TO HYDROTHERMAL INPUT FROM THE SEA FLOOR. THE SILL DEPTH OF THE BASIN IS LOCATED AROUND 1600M. INTERESTINGLY, THIS IS ALSO WHERE WE CAN SEE AN INCREASE IN ALMOST ALL PARTICLE VOLUMES (GIVEN A CERTAIN PARTICLE SIZE). NOTE ESPECIALLY THE INCREASE AT THE SMALL END (SMALL PARTICLES). THE VOLUME CONTRIBUTED BY LARGER PARTICLES ALSO INCREASE, BUT DOES SO MORE GRADUALLY, NOT AS A SHARP INCREASE THAT COREELATES WITH THE SILL DEPTH. IT IS POSSIBLE THAT THE CONCENTRATION OF THE LARGER PARTICLES ARE AFFECTED BY THE HYDROTHERMAL INPUT.
THERE ARE A FEW PROBLEMS WITH HOW WE USED/DEPLOYED THE LISST-DEEP. ONE OF WHICH IS THAT THERE IS ONLY SO FEW LARGER PARTICLES IN THE DEEP SEA THAT THE NUMBERS WE OBTAINED ARE BELOW THE DETECTION LIMIT THAT WAS POSSIBLE TO OBTAIN WITH OUR PROTOCOL. WHEN THAT IS THE CASE, THE DATA ARE DISPLAYED IN WHITE ONLY. THAT IS, TO RECAPITULATE, THE PART OF THE GRAPH THAT HAS COLOR IS GOOD DATA, WHILE THE PART THAT IS IN WHITE IS INFERED DATA.
