Unit 2 - MAB Case Study Flashcards
(23 cards)
What are some key features of the Mid Atlantic Bight?
Gulf Stream, Labrador Current, Shelf Break Front, Cold Pool, and Warm Core Rings.
What is discussed regarding seasonal cycles in the lecture?
The lecture discusses seasonal cycle stratification, including temperature and salinity evolution.
What is a Cold Pool?
A Cold Pool is a region of cold water, identified by a nominal 10 °C isotherm, that experiences seasonal variations.
What relationship does Sullivan et al. (2005) identify involving Yellowtail flounder?
They relate Yellowtail flounder abundance to colder bottom temperatures.
What effects do atmospheric forces have on the Cold Pool?
Atmospheric forcing is related to changes in the MAB Cold Pool
What can increase productivity in the Mid Atlantic Bight?
Upwelling
What is noted about Warm Core Rings?
Warm Core Rings are observed to have spatial seasonal patterns related to Gulf Stream activity.
How does the Cold Pool evolve seasonally?
The Cold Pool evolves with varying temperatures and density, influenced by seasonal cycles.
What is the purpose of repeat glider transects?
utilized to observe changes in density distribution.
What do upwelling processes lead to according to the lecture?
Upwelling processes lead to increased biological productivity in the region.
What is indicated about the interannual variability of Cold Pool features?
There are strong and weak Cold Pool years that affect ecological dynamics.
How does seasonal stratification affect the Mid Atlantic Bight?
Seasonal stratification influences temperature, salinity, and the ecological processes present in the region.
What seasonal patterns are observed with Warm Core Rings?
There are specific spatial seasonal patterns associated with the presence of Warm Core Rings.
What aspect of temperature evolution is considered in the lecture?
Seasonal temperature evolution is considered important for understanding the region’s ecology.
What role do plumes play in the Mid Atlantic Bight?
Plumes introduce warm, fresh water and can influence local marine conditions.
What does the Cold Pool affect in terms of marine biology?
The Cold Pool affects species distribution, such as the Yellowtail flounder.
How is recruitment related to biological data in Sullivan et al. (2005)?
Recruitment is linked to temperature conditions that affect Yellowtail flounder populations.
What does the term “subseasonal dynamics” refer to?
short-term changes in marine conditions, including upwelling and cold pools.
What is essential to understand regional-scale features in oceanography?
A variety of observations are necessary to understand regional-scale features.
What kind of changes are associated with seasonal dynamics?
dominant physical changes associated with seasonal shifts in the region.
What is an important consideration for ecological research in the Mid Atlantic Bight?
It is important to consider the interactions between temperature, salinity, and biological communities.
How does the Gulf Stream influence local marine ecosystems?
The Gulf Stream impacts temperature, nutrient distribution, and biological productivity.
What are some challenges noted in understanding oceanic processes?
The need for diverse observations to capture complex dynamics is a noted challenge.
