Overview
These plot measurements describe above-ground biomass, below-ground biomass and sediment carbon across four coastal seagrass meadows.
The record supports comparative blue-carbon research and keeps field measurements distinct from later scaling or stock estimates.
Method
Quadrats are surveyed during annual field visits, with biomass subsamples processed in the laboratory. Sediment cores retain depth, bulk density and carbon concentration alongside the plot record.
Field guide
| Field | Description |
|---|---|
plot_id |
Identifier for the sampling plot. |
biomass_g_m2 |
Measured seagrass biomass. |
sediment_c_pct |
Carbon concentration in the sediment sample. |
survey_year |
Year of the field survey. |
Known limitations
Plot observations do not represent the full meadow without an explicit scaling step. Seasonal timing and core depth should be retained when comparing sites.
概览
这些样地测量记录了四个滨海海草草甸的地上生物量、地下生物量和沉积物碳含量。
该记录适合蓝碳比较研究，并将野外测量与后续尺度转换或储量估算明确区分开来。
方法
研究人员在每年野外调查期间测量样方，并在实验室处理生物量子样。沉积物岩心记录深度、容重和碳浓度，并与样地记录关联。
字段指南
| 字段 | 描述 |
|---|---|
plot_id |
采样样地的标识符。 |
biomass_g_m2 |
测得的海草生物量。 |
sediment_c_pct |
沉积物样本中的碳浓度。 |
survey_year |
野外调查年份。 |
已知局限
如果没有明确的尺度转换步骤，样地观测不能代表整个草甸。比较不同地点时，应保留季节时间和岩心深度信息。
