This document discusses sightings of gray whales in San Francisco Bay from 1999-2001. A small number of gray whales have been observed foraging and traveling in the Bay, rather than making the full migration between breeding grounds in Baja California and feeding grounds in Alaska/Russia. Several whales were identified through photo ID but observing behavior made this difficult. Some whales stranded and died in the Bay, with causes including domoic acid poisoning and collisions. Future work is needed to better understand these whales' residence times, prey, and health risks of contaminants in the Bay.

A presentation before the Coconino County Board of Supervisors (Arizona) by David McKee of the City of Flagstaff on November 16, 2010. A resolution in support of Picture Canyon was adopted by the the Board.
This presentation explains how building the St. Lawrence Seaway and allowing ocean freighters into the Great Lakes in 1959 unleashed one of the world's worst environmental disasters.
During my term of service as an AmeriCorps Watershed Ambassador, I had the opportunity to assist researchers from the Rutgers University Marine Field Station with their weekly “bridge-netting” survey at Little Sheepshead Creek to monitor larval fish ingress from offshore spawning areas into Little Egg Inlet. For my host agency partnership project, I used data from this survey to develop a PowerPoint presentation to be used as an educational resource to explain the effects of climate change on local fisheries and estuaries. It was offered to educators attending professional development workshops at the Jacques Cousteau Coastal Education Center in Tuckerton, NJ during the summer of 2014.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Editor's Notes
This is a satellite photo of San Francisco Bay. The Bay is approximately 100 km long and up to 20 km wide and most of it is surrounded by highly developed urban areas. Over 6 million people live in the Bay area. San Francisco is located here San Jose and Silicon Valley form a horseshoe surrounding the southern end of the Bay with the Five bridges span the Bay and it is a major port. Many large tankers enter and depart through the Golden Gate each day and ferries crisscross the Bay on an hourly basis. Clearly, this is a place heavily dominated by mankind. While there are many reasons why millions of travelers visit the Bay area each year, I would venture to guess that not a single one of them came to go whale watching within the Bay. This may change, for gray whales are increasingly coming into San Francisco Bay. But let’s step back for a moment
1994 California Gray Whale was first cetacean species to be removed from U.S. Endangered Species List. Only the eastern population was delisted, for as Dave Weller reported the western population remains critically endangered. Current population estimate is 26,000 whales. Undertakes long migration between breeding lagoons along Baja California and foraging grounds off coasts of Alaska and Russia. Not all members of the population make this full migration as work of Darling, Calambokidis, Goley, their students and others has clearly shown. Indeed numerous individuals greatly shorten their migration by stopping at locations off the coast of northern California, Oregon, Washington, British Columbia and Alaska where they forage throughout the summer. Many of these same individuals have been observed to return to the same foraging site year after year.

This graph represents the number of days gray whales were reported in San Francisco Bay during 1999, 2000 and 2001. In 1999 whales were reported in the Bay on 39 days with the peak in April when they were reported on 9 days. In 2000 whales were reported on 69 different days with peaks in April and May and in 2001 they were reported on 98 days.with the peak in March. Typically the first whales are reported in late January as occurred in 1999 or early to mid February as occurred in 2000 and 2001
