Kuelewa Data za Satelaiti na Mazingira katika MariMap

MariMap hutoa data za satelaiti na mazingira kutoka NOAA Coral Reef Watch na Copernicus Marine Service, ikijumuisha sea surface temperature, salinity, chlorophyll, pH, currents, na heat stress indicators. Mwongozo huu unaeleza data ipi inapatikana, jinsi ya kusoma chati na condition categories, na jinsi ya kutumia muktadha wa mazingira kwenye maamuzi ya uhifadhi wa bahari. Vyanzo vyote vya data vinatajwa na kuunganishwa kwenye ukurasa wa marejeo wa MariMap.

Uwasilishaji wa data za mazingira katika MariMap.

Kwa muhtasari

• Data za satelaiti zinaunganishwa na site boundaries na observation units.
• NOAA Coral Reef Watch hutoa heat stress indicators za maeneo ya miamba ya matumbawe.
• Copernicus Marine Service hutoa vigezo vya bahari kwa upana zaidi.
• condition categories hutoa muhtasari wa jinsi hali ya sasa ilivyo ya kipekee.
• Tumia muktadha wa mazingira kuelezea matokeo ya survey na kupanga kazi ya uwanjani.

Mahali pa kupata data za satelaiti kwenye MariMap

• Site page: fungua site na angalia kichupo cha Satellite time series.
• Analytics: tazama mienendo ya mazingira sambamba na survey metrics.
• Maps: ongeza environmental layers kwa muktadha wa kikanda inapopatikana.

Data za satelaiti zinaunganishwa na site boundary, hivyo site geometry sahihi ni muhimu.

Watoa data

NOAA Coral Reef Watch (NOAA CRW)

NOAA Coral Reef Watch hutoa bidhaa za kimataifa za heat stress zilizobuniwa kwa ufuatiliaji wa miamba ya matumbawe.

Data zinazopatikana:

• Sea surface temperature (SST)
• SST anomaly
• HotSpot
• Degree Heating Week (DHW)
• Bleaching alert indicators

Bora kwa: coral reef na seagrass sites.

Copernicus Marine Service (CMEMS)

Copernicus Marine Service hutoa bidhaa za bahari za near‑real‑time na forecast.

Data zinazopatikana:

• Sea surface temperature (SST)
• Salinity
• Chlorophyll‑a concentration
• pH
• Surface current speed

Bora kwa: mangrove sites na muktadha mpana wa bahari.

• Copernicus Marine Service

Tabaka za ardhi ya pwani na shinikizo la binadamu

MariMap pia huunganisha ishara za ardhi ya pwani na tabaka za shinikizo la binadamu inapopatikana.

Understanding environmental condition categories

MariMap summarizes current conditions using simple categories per parameter: OK, WATCH, and ALERT. These categories are derived from a z-score comparison against a seasonal baseline (they are not a score).

Method summary:

1. Baseline: 365-day lookback with a seasonal window.
2. Z-score: (current value - baseline mean) / baseline standard deviation.
3. Category thresholds:

• OK: |z| < 1
• WATCH: 1 ≤ |z| < 2
• ALERT: |z| ≥ 2

Use the category as a quick signal and always refer back to the raw values and local measurements.

Heat stress indicators

Maximum Monthly Mean (MMM)

Kiwango cha juu cha wastani wa SST wa mwezi, kinachotumika kuhesabu bleaching threshold.

Degree Heating Week (DHW)

Heat stress iliyokusanywa kwenye dirisha la siku 7, hupimwa kwa °C‑weeks.

DHW ni kiashirio kinachotumika sana kwa hatari ya coral bleaching.

HotSpot

Halijoto iliyo juu ya bleaching threshold. HotSpot husaidia kutambua matukio ya haraka ya heat stress.

Kutumia data za mazingira kwenye maamuzi

Kupanga field work

• Epuka surveys wakati wa peak heat stress.
• Panga baseline surveys kabla ya msimu wa joto kuongezeka.
• Panga outplanting ya restoration wakati hali ni thabiti.

Kufasiri matokeo ya survey

• Linganisha mabadiliko ya coral cover na heat stress indicators.
• Tumia SST na chlorophyll kuelezea mabadiliko ya msimu.
• Tambua hali zisizo za kawaida zinazoweza kuathiri fish au benthic communities.

Reporting

Ongeza muktadha wa mazingira kwenye ripoti ili kuelezea mwenendo unaoonekana. Data za satelaiti husaidia wafadhili na wadhibiti kuelewa matokeo ya survey.

Masuala ya kawaida

• Hakuna data: baadhi ya sites zinahitaji muda kujaza historia.
• Facility sites: facilities za ardhini hazipati data za satelaiti.
• Sparse signals: data za karibu na pwani zinaweza kuwa noisy; tumia viashirio vingi.

MRV readiness and disclosure alignment

• Baseline vs repeat surveys: mark baselines and keep repeat surveys on comparable geometry.
• Monitoring plan logic: define cadence, QA/QC thresholds, and conservative handling of uncertainty.
• Outcome types and claims discipline: record uplift, avoided loss, or maintenance credits; separate inputs from verified outcomes.
• Rights and integrity: document FPIC, customary marine tenure, OECM, ICCA, benefit sharing, durability mechanisms, and leakage risk.
• Disclosure alignment: map indicators to TNFD, CSRD, ESRS, EU Taxonomy, SBTN, and SBTi requirements.
• Use the Metrics Reference and Data Providers for definitions and sources.
