Climate Change Impacts on New Jersey’s Commercial Fisheries:
Coastal fishing communities in New Jersey are witnessing the effects of climate change first-hand. They face increased flooding, coastal storms, rising sea levels, and shifts in fish populations. These impacts directly affect their working waterfronts, causing infrastructure damage and disruptions in transportation. Furthermore, as ocean waters warm, commercially valuable species like summer flounder are migrating, necessitating adaptation by commercial fishers.

Economic Repercussions:
The New Jersey commercial fishing industry generates an estimated $4.5 billion annually from fisheries, aquaculture, and recreational fishing. Any adverse impacts on this industry will reverberate through the state’s economy, affecting livelihoods and communities.

Scientific Support for Resilience:
To assist those engaged in the commercial fishing industry in mitigating climate change effects, the Rutgers team collaborated with fisheries resource managers and industry stakeholders to create the Resilience Checklist. This checklist enables fishers and businesses to identify opportunities for improving resilience to storms, coastal hazards, and changes in fish productivity and distribution. By completing the checklist collaboratively, fishing businesses from a specific New Jersey port or dock can foster conversation and coordination on planning and preparation to address vulnerabilities.

Planning and Preparation for Resilience:
Coastal hazards are an inherent part of coastal living, but climate change threatens to increase their intensity and frequency. Planning and preparation play a crucial role in improving resilience. By proactively addressing vulnerabilities, such as damage to land-based infrastructure or disruptions to operations, fishing businesses can bounce forward from coastal hazard events. By rebuilding in stronger, smarter, safer, and more resilient ways, they can resume operations swiftly.

Moving Forward:
New Jersey’s fishing industry has continuously adapted to change since the 1600s. The distribution of the Resilience Checklist and the development of an interactive story map by Rutgers scientists will empower commercial fishers, ports, docks, and fisheries scientists and managers to assess and enhance their resilience. This guided approach encourages reflection on existing measures taken to build resilience and identifies opportunities for further preparation to address current and future risks.

As climate change impacts continue to reshape New Jersey’s coastal environment, the collaborative efforts between Rutgers scientists and the commercial fishing industry provide a vital foundation for resilience. By leveraging scientific expertise and fostering proactive planning and preparation, the industry can navigate the challenges ahead, safeguard its economic contributions, and ensure the sustainability of coastal communities for generations to come.

Asteroid Apophis: An Exciting Encounter with Earth

Location, Location, Location:
Apophis is an asteroid measuring about 1,100 feet (340 meters) in diameter. Extensive calculations have revealed that it will safely pass by Earth both in 2029 and 2036. During the 2029 flyby, Apophis will come within a nominal distance of 19,662 miles (31,643 km) from our planet’s surface, closer than the moon and many satellites in Earth’s orbit. As it traverses through Earth’s gravitational field, the passage of Apophis might even cause subtle asteroid-quakes and slightly alter its orbit.

Spectacular Viewing Opportunities:
Although not observable from everywhere, lucky viewers in Australia, southern Asia, southern Europe, and Africa will have a front-row seat to witness Apophis at its brightest in 2029. As the asteroid gradually moves away from Earth and dims, it will become visible in eastern South America. Furthermore, as evening falls along the east coast of North America, telescopes will reveal Apophis located approximately 15 degrees north of the Pleiades. An ephemeris for the asteroid can be found on our website to help astronomers and enthusiasts track its celestial journey.

The Discovery of Apophis:
On the remarkable evening of June 19, 2004, astronomers at Kitt Peak National Observatory in Arizona made a thrilling discovery. Dave Tholen, Fabrizio Bernardi, and the late Roy Tucker stumbled upon an asteroid, later designated as 2004 MN4. What made this discovery even more extraordinary was the fact that the asteroid was unusually close to the sun, only 57 degrees away. Further observations revealed that Apophis had an orbit different from most asteroids, resembling that of an Aten-class asteroid.

Narrowing the Probability of Collision:
Initially, calculations showed that Apophis had a 2.7% chance of colliding with Earth on April 13, 2029, a date marked with superstition. This resulted in a media frenzy surrounding the potentially hazardous asteroid. However, over several years, astronomers meticulously observed Apophis, taking into account the influence of other celestial bodies and the Yarkovsky effect caused by sunlight. By 2006, these studies dispelled the notion of a collision in 2029, relieving the world of any imminent danger.

No More Worries for the Future:
Many eagerly awaited the subsequent close approach of Apophis in 2036. However, in 2013, after conducting radar observations using the Goldstone Deep Space Communications Complex and the Green Bank Observatory, NASA definitively ruled out any potential impact in 2036 and for the next 100 years. Apophis is now no longer on the Sentry Impact Risk Table, which lists potentially dangerous objects near Earth.

Unlocking the Scientific Opportunities:
With the new knowledge that Apophis poses no threat, astronomers can fully embrace the upcoming close encounter as a fantastic scientific opportunity. The OSIRIS-REx spacecraft, known for its historic mission to bring samples from asteroid Bennu back to Earth, is now en route to rendezvous with Apophis in April 2029. Renamed OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification, and Security – Apophis Explorer), this mission will unlock further insights into the asteroid’s composition and characteristics.


As we eagerly anticipate the visit of the asteroid Apophis in 2029, let us celebrate the wonders of our universe. Apophis serves as a reminder of the dynamic nature of our cosmic neighborhood and the continuously advancing knowledge of our exceptional astronomers. So mark your calendars and join the world in witnessing this extraordinary celestial event, which promises to be a captivating spectacle for all.

What is California High-Speed Rail?

The California High-Speed Rail (CAHSR) is a state-funded project led by the California High-Speed Rail Authority. Currently under construction, Phase 1 is planned to cover 494 miles from San Francisco to Los Angeles, passing through the Central Valley. There are plans for Phase 2, which would extend the system to Sacramento and San Diego, totaling 776 miles. Authorized by a 2008 ballot, this ambitious project aims to connect major urban areas, significantly reducing travel times. The goal for Phase 1 is to achieve a travel time of 2 hours and 40 minutes between San Francisco and Los Angeles, a vast improvement from the existing Amtrak service, which takes around nine hours.

Construction of Phase 1 began in the Central Valley back in 2015. The project is being built in sections due to limited funding. The state aims to complete a 171-mile (275 km) long Initial Operating Segment (IOS) connecting Merced and Bakersfield by 2024. The IOS is expected to begin its revenue service as a self-contained high-speed rail system between 2030-2033, at an estimated cost of $28–35 billion. CAHSR trains running along this section would be the fastest in the Americas, with a top speed of 220 mph (350 km/h).

Between January 2015 and December 2023, a whopping amount of $11.2 billion was spent on the IOS project, which includes 119 miles (192 km) currently under construction, alongside upgrades to the existing rail lines in the San Francisco Bay Area and Greater Los Angeles. The plan is that Phase 1 will share tracks with conventional passenger trains. However, the Authority has not yet secured funding to connect the Central Valley section with either the Bay Area or Los Angeles, which involves crossing several major mountain passes. As of 2024, it is estimated that Phase 1 will cost a total of $106.2 billion.n.

Supporters of the California High-Speed Rail project emphasize the potential benefits it offers, including the reduction of air traffic and highway congestion, decreased pollution and greenhouse gas emissions, and the promotion of economic growth by connecting inland regions to coastal cities. However, opponents argue that the project is too expensive and advocate for directing funds to other transportation or infrastructure initiatives. The choice of route and the decision to initiate construction in the Central Valley, rather than more densely populated areas, have been points of contention. The project has encountered notable challenges such as delays and cost overruns due to management issues, legal disputes, and a lack of complete funding commitment.

The tunnelling process for the Purple Line has significantly progressed, thanks to advancements in tunnel boring machines (TBMs). These colossal drills, equipped with giant cutter heads, have improved safety, speed, and sustainability. Compared to earlier methods, modern TBMs utilize an ‘earth pressure balance’ technique, ensuring constant pressure in the surrounding soil during excavation. This progress allows for a sturdy, secure tunnel construction.

Completing Section by Section:
The project is divided into three sections, each unveiling a distinct aspect of Los Angeles’ history. Section 1, stretching from Wilshire/La Brea to Wilshire/Western, uncovered a trove of over 2,000 fossils, including mammoths, dire wolves, and giant sloths. Additionally, numerous anomalies were discovered, such as mysterious steel beams buried beneath the ground. Section 2, between La Cienega Avenue and Century City, revealed remnants of Century City’s past as it evolved from a former backlot. Beverly Hills High School also held abandoned oil wells, highlighting L.A.’s oil-rich history. Finally, Section 3 unearthed remnants of structures from the National Home for Disabled Volunteer Soldiers and Sailors, providing a glimpse into late 19th-century architecture.

Overcoming Challenges:
Excavating through tar-soaked soil presented immense challenges during the tunneling process. However, with perseverance, innovation, and new techniques, the TBMs successfully navigated 10 miles beneath the surface. Remarkably, this feat was accomplished without any complaints of noise or vibrations, a testament to meticulous planning and consideration for the surrounding communities.

Cultural and Historical Significance:
Los Angeles has a unique relationship with its underground realm. From the tar pits of Hancock Park to the city’s identity as an urban oil field, the subterranean world influences the collective psychology of Angelenos. The completion of the Purple Line tunnels represents a continuation of this connection between past and present. The underground holds a powerful allure, filled with fascination, myths, and hints of what the future holds.


The Purple Line Extension Project is not just a transportation endeavor; it is a historic achievement for Los Angeles. Overcoming hurdles, preserving fossils, and unearthing remnants of the city’s past, this project symbolizes the city’s unwavering dedication to creating a comprehensive, efficient, and sustainable transit system. As the final phases of construction and station development progress, the Purple Line will connect communities, create opportunities, and leave an indelible mark on the city’s history.
