BEERSHEVA — An off- beat connection ties cold, windswept Mars, the Earth's nearest planetary neighbor, with Israel's des- ert university, Ben-Gurion University of the Negev. That link is Dr. Haim Tsoar, resident sand dune expert. Tsoar, whose specialty is aeolian geomorphology — the effect of wind action on the earth's surface — used the knowledge he gained while closely observing dunes in the Sinai to deter- mine the wind direction on Mars by studying its sand dunes. Tsoar's fascination with dunes began during the Six-Day War when, stationed in the Sinai, he caught himself wondering what processes create dunes and cause them to migrate. At the time, he was casting around for a subject for his nis hotel and R ten club .

"The dunes I'm par- ticularly interested in," explains Tsoar, a member of the BGU geography department, "are the ones known as linear or 'seif dunes, which are the most wide- spread type of dune in the world's deserts. Seif is an Arabic word meaning sword and these dunes were so named because they resemble a curved- bladed, sword whipping its way through the des- ert." "I found it very easy," Tsoar recalls, "to study the movement of the dunes from Ben-Gurion University, which is conveniently lo- cated in the midst of a des- ert. I would drive 100 miles into the Sinai, position my equipment, which included a wind recorder for measur- ing velocity and direction, smoke candles, small-cup anemometers, and the use of fluorescent-dyed sand as a tracer, drive back into Beersheva and wait for a sand storm." "Since the dunes were so accessible I could obtain, through my experiments, accurate, scientific meas- urements which I followed over a three-year period. Tsoar was called on by NASA, while he was in the United States doing post- doctoral work, to join the team analyzing the many thousands Of photos trans- mitted back to Earth by the Viking mission to Mars which took place during 1976-1980. Tsoar con- cluded, utilizing experience gained with Sinai's dunes, that the Martian dunes are active and subjected to more than one wind direction. The summer winds on Mars blow from the north pole southward and, in addition 3,000 Protest Anti-Semitism LOS ANGELES (JTA) — More than 3,000 people gathered at the Simon Wie- senthal Center for Holocaust Studies at Yeshiva University of Los Angeles for a rally last week against anti-Semitism and bigotry. Wiesenthal flew from his home in Vienna to be the featured speaker at the rally. The program also in- cluded civic, religious and community leaders who participated in a cleansing ceremony of the desecration that occured at the center earlier this month.
