1.Multiple sources contribute; CO2 is primary but not sole
cause
2.Excess nutrients cause eutrophication and dead zones
REFSTUDY GUIDE: Big Ideas (W1-W5)Review before assessment
1.All biogeochemical cycles are interconnected.
Changes in one affect others (carbon -> acidification, nitrogen ->
eutrophication).
2.Human activities add inputs faster than sinks can process
them.
We're disrupting billions-year-old equilibrium.
3.Small quantitative changes produce large ecological
impacts.
pH 0.1 units, NDVI +/-0.1 matter enormously.
4.Multi-scale monitoring enables early detection and
solutions.
Ground + drone + satellite systems working together.

WRITESYNTHESIS PHENOMENONConnect W1-W5 concepts
How do interconnected biogeochemical cycles respond to human
impacts, and how can monitoring help design solutions?
This week brings together everything from W1-W5: carbon and nitrogen
cycles, ocean acidification, eutrophication, dead zones, and remote
sensing. You'll trace how a single human decision (burning fuel,
applying fertilizer) ripples through multiple interconnected
systems.
Your initial thinking - what connections do you already see?

CHECKDAY 1 CHECK-INComplete after Station 1
Q1:How does burning fossil fuels affect BOTH the carbon cycle AND
ocean acidification? Trace the connection.
Q2:Why do BOTH nitrogen AND phosphorus cause eutrophication? What do
they have in common?

Q1 (CUMULATIVE):Trace a farmer's fertilizer decision through: nitrogen cycle ->
water quality -> dead zones -> coastal economies.
Q2 (MONITORING):Design a multi-scale monitoring system for W1-W4 problems. What
would ground, drone, and satellite each detect?
Q3 (INTEGRATION):Explain how fossil fuels AND fertilizer TOGETHER damage ocean
ecosystems (two different pathways).
