GVSU faculty and area experts provide engaging ideas on current topics in research and education

Finding a Lake's Productivity Peak and Nap TimeBY BOPI BIDDANDA AND ANTHONY WEINKE, ANNIS WATER RESOURCES INSTITUTE

Lakes contribute disproportionately to global cycling of elements, more than their relatively small surface area would otherwise suggest.  Natural and

anthropogenic sources of runoff from the watershed create a strong terrestrial contribution to aquatic productivity.  Tiny but abundant plankton link

the water and airsheds to the food webs in the the receiving lake through their growth and respiration – collectively called metabolism.  Because of

their intimate connection to the land, freshwater lakes are particularly active sites for the cycling of organic carbon and inorganic nutrient inputs –

and serve as sensitive sentinels of change in their collective water and airsheds.

The 10,000 miles of Great Lakes’ shoreline are intersected by almost 3,000 tributaries. One of these intersections is Muskegon Lake.  It is fed by the

Muskegon River, the second longest river in Michigan and drains an area of ~ 6,000 km2 (Figure 1) into Lake Michigan.   As the receiving basin for a

large watershed, Muskegon Lake is a concentration point for vast amounts of terrestrial organic carbon and inorganic nutrients delivered by the

Muskegon River.  Thus, variable river discharge can potentially fuel highly variable rates of productivity and respiration by in-lake phytoplankton and

bacteria, respectively.

Figure 1.  Map of Muskegon Lake study area and sample locations: Muskegon River, Muskegon

Channel and Muskegon Deep, with Lake Michigan in the foreground.  Inset: Laurentian Great

Lakes basin, with boxed area highlighting location of Muskegon Lake located at the terminus of

Muskegon River watershed (gray shaded area in the state of Michigan).

Figure 2a.  Graduate Student, Angela Defore sampling Muskegon Lake water and incubating lake

water-filled bottles underwater through an ice hole during the winter. Winter is the most

understudied portion of the annual cycle in temperate latitude lakes. 

Figure 2b. Site averaged Chlorophyll a (an index of phytoplankton biomass) in the surface waters

of Muskegon Lake from February 4, 2009 – February 11, 2010.  Error bars represent 1 standard

error.

We examined monthly changes in biological inventories and community metabolism in Muskegon Lake – including during the ice-covered winter

season and found that there was a positive buildup of phytoplankton biomass during spring through fall (Figure 2). 

Similarly, rate measurements indicated that net production dominates (Production > Respiration) during the spring, summer, and fall seasons, whereas

net respiration is only slightly dominant during the winter months (Figure 3).  This results in net annual autotrophy (i.e., surplus production) in the

ecosystem as evidenced by the accumulation of phytoplankton biomass.  It additionally suggests, that the surface waters of Muskegon Lake may be a

“carbon sink”, which buries carbon in its sediments, or exports it to Lake Michigan supporting nearshore metabolism.

Figure 3.  A.  Conceptual diagram of trends in

the seasonal metabolism (Gross Primary

Production, GPP and Respiration, R; A) and

represented as the ratio of GPP:R (B).  The

1:1 line indicates the zone of carbon balance

above which net production (autotrophy)

prevails and below which net respiration

(heterotrophy) prevails. 

These findings also shed light on a seriously understudied component of the annual cycle of lakes:

the key role of winter months in nutrient regeneration that subsequently fuel spring production. 

Future studies should reassess the critical role of winter months as an annual  “reset button” for

the lake ecosystem as whole.  The in-lake regeneration of nutrients during winter, spring-time

nutrient loading from the Muskegon River watershed, increased summer-time sunlight

availability, and favorable residence time (2-4 weeks) enable optimal retention of resources and

completion of plankton and fish life cycles within Muskegon Lake (Figure 4).  All these factors

converge to make this Great Lakes estuary a zone of net annual primary productivity in the

watershed, supporting one of the most productive fisheries in the state.  Similar phenomena may

be at play in inland waters and coastal estuaries everywhere where food web productivity is tied

to peaks of primary production.  Therefore, understanding the delicate dance between autotrophy

(Production > Respiration) and heterotrophy (Respiration > Production) in lake and estuarine

ecosystems that are sentinels of change in their air and watersheds will be key to their wise

management in an uncertain future.

For further details, please see (below) the peer-reviewed journal article that is openly accessible.

This research effort was supported by a NASA Michigan Space Grant Consortium Seed Grant and

an EPA Great Lakes Restoration Initiative Grant to BB, and a MSGC Graduate Fellowship and a

GVSU Presidential Research Grant to Angela Defore.

Figure 4. Schematic illustration highlighting the seasonal succession of life in temperate lakes.  Life awakens from the winter’s nap into spring growth,

followed by summer-fall’s peak biomass, ending in the cold and slow holiday season towards the year end.  Winter months serve as a system reset

wherein inorganic plant nutrients are regenerated from net respiration of organic matter.  Spring through fall, these plant nutrients are consumed –

resulting in net production of biomass containing organic carbon  that sustains a diverse and productive food web.

A CELEBRATION OF SPACE EXPLORATION INHONOR OF ROGER B. CHAFFEEFEBRUARY 10-11, 2017

Roger B. Chaffee was born in 1935 in Grand Rapids, Michigan and became one of the city’s

favorite sons. An engineer, pilot and astronaut, Chaffee lost his life during a tragic fire during what

seemed to be a routine test of the Apollo 1 spacecraft on January 27, 1967.

In recognition of the 50th anniversary of the Apollo 1 accident, Grand Valley State University, the

Grand Rapids Public Museum and the Roger B. Chaffee Scholarship Fund seek to honor Chaffee

during a two-day celebration of space exploration.

“Roger That!” is a series of concurrent events to be held in downtown Grand Rapids on Friday

February 10 and Saturday February 11, 2017.

Field trips involving area schools will also be scheduled, allowing local students the opportunity to learn about space exploration through a series of

programs held at the Grand Rapids Public Museum, including hands-on activities and a presentation at the Roger B. Chaffee Planetarium. The

following day, Saturday, family events focusing on space will continue at the GRPM.

Visit the celebration website at www.gvsu.edu/rogerthat for more information.  For questions, contact rogerthat@gvsu.edu.

Event Details

On Friday February 10, The L.V. Eberhard Center and Kennedy Hall of Engineering will hold an Academic Conference from 8 am to 5 pm. Fifteen

academics from a number of different fields will present papers during five breakout sessions that cover the themes “Space and Science,” “Space and

Society” and “Space and the Arts.”

The afternoon Keynote Address, “Why Do We Look Up At the Heavens?” will be presented by Brother Guy Consolmagno, the Director of the Vatican

Observatory and a renowned expert in the field of planetary science. His books include Brother Astronomer: Adventures of a Vatican Scientist and

Would You Baptize an Extraterrestrial? Brother Consolmagno received the Carl Sagan Medal from the American Astronomical Society in 2014.

A Student Design Challenge will be held that allows local students in grades 6 -12 to show off their innovative solutions to a choice of three challenge

topics: Humans in Space, Communities in Space and Robots in Space. Solutions will be presented and displayed on posters in Kennedy Hall on Friday.

Both juried and public voting will take place with the winners announced at the Grand Rapids Public Museum on Saturday. Design Challenge guidelines

and instructions for educators can be found on our website.

A Friday evening catered dinner at the Eberhard Center will be held, followed by a keynote address entitled “A Conversation with Martha and Sheryl

Chaffee.” Martha Chaffee is the widow of Roger B. Chaffee, and Sheryl is their daughter.  Sheryl has spent over thirty years working for NASA. Both

women are supporters of the Astronaut Memorial Foundation. We are delighted to have them attend our event in Roger’s honor. The dinner and

keynote together form a single ticketed event with proceeds going to the Roger B. Chaffee Scholarship Fund. Space is limited so those planning to

attend the dinner event are encouraged to register early on our website.

Following the Friday keynote, the Grand Rapids Pubic Museum will present “Dark Side: The Light Show” at the Roger B. Chaffee Planetarium beginning

at 9 pm.

On Saturday, February 11, “Roger That!” will continue at the Grand Rapids Public Museum, with educational exhibitions and activities scheduled to

take place throughout the day. The general public, families in particular, are encouraged to attend. Events will include a public talk by Brother Guy

Consolmagno entitled "Discarded Worlds: Astronomical ideas that were almost correct."

In addition to all of the above, samples from the Moon and beyond will also be coming to the Grand Rapids area as part of the “Roger That!” event.

GVSU will be receiving two clear acrylic discs from NASA’s Astromaterials Acquisition and Curation (ARES) Office in Houston. One disc contains lunar

material (three soils and three rocks) gathered from the various manned Apollo lunar landing sites, while the second disc contains assorted meteorite

samples. These rare materials will be accessible for viewing by the public during scheduled display times on both days of the event.

Finally, in advance of the February event, a special “Roger That!” photo exhibition will be on display from January 1 through March 31 at the West Hall

Gallery in the Eberhard Center. The exhibition, produced by the GVSU Art Gallery in conjunction with the Chaffee family and the Grand Rapids Public

Word Problems, Children's Strategies, and UnderstandingAddition and SubtractionA WORKSHOP FOR ELEMENTARY SCHOOL TEACHERS (ESPECIALLY GRADES K-2), MATHCOACHES, & ADMINISTRATORS

Dates: January 11th & February 1st, 2017

Time: 8 am - 3 pm

Workshop Description:

The CCSSM states that elementary school students need to be able to solve addition and subtraction word problems involving situations of adding to,

taking from, putting together, taking apart, and comparing with the unknown in various places.  Are your students able to readily understand and solve

some of these types of word problems but not others?  What makes some word problems more accessible or more challenging to children than other

problems?  How might word problems be effectively used to help children understand addition and subtraction and develop strategies for solving

these problems? 

We will explore a framework for the different types of addition and subtraction word problems, which was developed as part of the Cognitively Guided

Instruction research project and provides the basis for the CCSSM standard above.  These explorations will help us view addition and subtraction from

a child’s perspective and to identify levels of difficulty associated with the different types of addition and subtraction word problems.  We will also

explore factors that are important to consider to effectively used word problems to help children understand and develop strategies for solving

addition and subtraction problems.

Participants will be provided with time to develop sets of word problems that they will use with students in their classrooms.  Participants will also

have time to share and reflect on their experiences using word problems to develop and extend their students’ understanding of addition and

subtraction.

This workshop was created using materials from the Cognitively Guided Instruction (CGI) research project and NCTM publications.

Facilitator:

Nancy K. Mack., Professor of Mathematics, GVSU

Nancy received her doctoral degree from the University of Wisconsin-Madison with a major in Curriculum & Instruction (emphasis in Mathematics

Education) and a minor in mathematics.  Nancy has been a faculty member in the Department of Mathematics at GVSU since 2001.  Additionally,

Nancy volunteers in an elementary school in GRPS where she teaches weekly enrichment lessons to whole classes of children.  Nancy is highly

interested in helping children learn about numbers and operations on numbers in ways that are meaningful to them.

Making SquaresMs. Harper needs a large number of congruent squares for a craft project for her students. She finds a large piece of cardboard that measures 588 cm × 630 cm. She would like to use all the cardboard, with no waste, and wants the squares to be as large as possible.

1. What are the dimensions of the largest squares that Ms. Harper cancreate without having any leftover cardboard? Remember that all squaresmust be congruent. How do you know that no other larger size is possible?

2. How many squares of that size will Ms. Harper be able to create?

Ms. Harper decides that a nonsquare rectangle might work better for herstudents’ craft project. She cuts the 588 cm × 630 cm piece of card-board into 108 congruent rectangles with no waste.

3. What are the dimensions of the rectangles that Ms. Harper could create?Are there any other dimensions she could have used? How do you know?
