The Mystery of the Oceanic Sunfish (Mola mola)
One of my most impactful experiences happened aboard the American Star on May 26, 2022. It was my third day as an intern at the Cape May Whale Watch and Research Center and Icould not wait to get out into the open waters. As we were leaving the inlet to enter the AtlanticOcean, that’s when…
Horseshoe Crab Spawning in New Jersey
The Atlantic Horseshoe Crab, also called by the scientific name Limulus polyphemus, are prehistoric animals that have been on Earth for millions of years. They are in the Phylum Arthropoda. The horseshoe crabs’ structure dates 245 million years ago in the Carboniferous Period and they are more closely related to spiders, ticks, and scorpions (Tanacredi, Bottom & Smith…
PCB Bioaccumulation and Cetaceans
What are PCBs? PCB stands for Polychlorinated Biphenyls, and represents a grouping of man-made chemicals that consist of carbon, hydrogen, and chlorine. PCBs were first produced in the late 1920’s / early 1930’s, and were continued to be used in products until its ban in 1979 (Toxic Substances Control Act) due to the toxicity of PCBs and its negative impacts on biological organisms. There are a range of PCBs, with varying consistencies (from a thin liquid to a thick wax) as well as varying degrees of toxicity. PCBs were very popularly used in a large variety of products due to their “non-flammability, chemical stability, high boiling point, and electrical insulating properties” (EPA). Some examples of products listed on the EPA’s website for things that previously contained PCBs include: · Pigments and dyes · Oil-based paint · Caulking · Plastics ·…
The Cownose Ray
The Cownose Ray, Rhinoptera bonasus, gets its name from the shape of its forehead, which resembles the nose of a cow. The top of the ray is a brown color, and the bottom is white. Females are 3 feet in width, and males are 2-and-a-half feet in width. They have long whip-like tails with…
The Breach of a Lifetime
5/15/21 – CMWWRC Database On May 15th, 2021, I witnessed a very rare event. Some would even say it was once in a lifetime sight. It seemed like just a normal day on the water while interning on the American Star for Cape May Whale Watch and Research Center. But, halfway through our trip, we…
Our Changing New Jersey Shorelines: More Than Moving Sand
A variety of processes contribute to the changing appearances of New Jersey’s beaches. Each year, some beaches grow while others shrink as a result of longshore drift gradually pushing sand from one shore point to the next. Nor’easters, hurricanes, and rising sea levels can exacerbate the process, removing massive sections of the beaches along the…
Working Towards a Greener Summer
It’s no secret that every summer, thousands of people from numerous different areas will flock to New Jersey beaches to enjoy the weather and take advantage of all the state has to offer. NJ’s vast coastal areas are one of the state’s greatest resources and the source of plenty of revenue each year. But…
Do Skin Lesions in Atlantic Bottlenose Dolphins Change?
Cape May, New Jersey is home to hundreds of Atlantic Bottlenose dolphins. Bottlenose dolphins are a migrating species of cetacean that travel to warmer weather in the winter. However, Cape May is where they come back to each year to give birth and raise their young. This makes Cape May a great location to study…
Share the Shores
Cape May is known for its gorgeous shorelines, beautiful Victorian architecture, and interesting history. Its no wonder that the summer months draw 40,000 to 50,000 visitors annually with a steady increase every year (Barlow 2019). While this is good news for the local economy and to the thousands of visitors who choose to vacation in Cape May, this excess foot traffic can be problematic for migrating shorebirds who nest on the coastlines. Adult Black Skimmer Shorebirds are some of the most migratory animals known to science today, and the habitats they utilize for nesting and feeding are extremely important to maintaining a healthy weight while migrating and for successfully raising chicks. Many of these vulnerable shorebirds have seen declines since the 1970s. Factors affecting these birds include degradation of their wintering or staging grounds through development, human disturbance, pesticide use,…
Otolith Age and Growth – Lab Report
Megan DeMatteo | Fisheries Science & Management Stockton University| May 3, 2019 Abstract The main objective of this study was to obtain a better understanding of otoliths, understand their important role in conducting research, and understanding the relationships between their growth rings and fish size. In this laboratory experiment otoliths will be identified, removed, embedded, polished, and analyzed to properly read through several microscopic lenses. The data collected was otolith length, width, and measurements were taken for each growth ring within their secondary growth center. When this data was compared to the overall fish size the results shown were a positive correlation between otolith growth and fish size. In simpler terms this means that as the fish grows so did its otolith rings. Another factor taken into consideration was although the data did show a positive relationship, once the fish…
